Can You Contest Facebook Marketplace Reviews? Platforms Compared
A buyer cannot contest Facebook Marketplace reviews in place: Facebook offers no edit and no appeal once a review is public. The only control is deletion, and a deleted review cannot be replaced for the same transaction. Contest platforms differ on their own checks: Gleam ships automatic fraud detection on every plan, SweepWidget verifies more than 50 data points per entry through device fingerprinting, and Woobox blocks votes from IP addresses flagged as fraudulent sources.

What Facebook lets a buyer change
Facebook's own help pages describe the buyer's control over a seller review narrowly. A review can be written once, posted, and then deleted at any time. Nothing in that description offers an edit button, an appeal form, or a moderation queue the buyer can join. The review becomes public once posted, and from that point Facebook states plainly that it cannot be edited. Contest the wording before publication, because afterwards the only lever left is deletion.
Deletion carries a cost the buyer should weigh first. If a seller review is deleted, before or after the seller replies, Facebook will not allow another review of that seller for the same transaction. A second, softer review cannot replace a harsh one. The decision is final in both directions, which is why the delete button is the closest thing this platform has to an appeals process.
- Publish with care: the text becomes public immediately and cannot be edited afterwards.
- Delete only after weighing the trade: no replacement review is possible for the same transaction.
- Treat the seller's reply, which Facebook's help text anticipates, as the counterweight to a posted review.
Ratings and the app-only rule
Ratings sit beside reviews and obey the same platform rule. Facebook states that buyer and seller ratings can only be provided from the Facebook app for iPhone or Android, not from a computer, a mobile browser, or Facebook Lite. Seller reviews share that restriction, since they are available only in the iPhone or Android app. Anyone planning to leave feedback after a Marketplace transaction needs the app installed first, whatever device the transaction happened on.
The app-only rule shapes disputes too. A buyer who wants to delete or manage a review will do it in the same app where the review was posted. There is no separate desktop workflow to fall back on, and no parallel route through the website.
How LeetCode contest ratings work
LeetCode handles contest standing differently from a Marketplace review, and its mechanics are public. A user's contest profile shows a Contest Rating figure together with an Attended count. Inside a contest, ranking is decided by the score reached and the finish time, with a more challenging problem carrying a higher score and fewer mistakes counting in the participant's favour. The objective, as LeetCode's support pages put it, is the highest score with the fastest finish.
The rating itself travels across seasons. LeetCode has stated that all contest seasons share the same rating algorithm, so a rating earned in one season is measured against the same yardstick in the next. Each contest participant plays against each of the other participants for rating, which is what makes the figure comparable between two accounts that have never met in the same round.
LeetCode also announced in 2020 that a new rating algorithm would not be implemented immediately, a reminder that platform numbers change on the platform's schedule, not the participant's.
- Contest Rating appears on the account's contest profile page.
- Attended counts how many rated contests the account has played.
- Score, finish time and mistake count decide the rank inside a single round.
Rated or unrated on Codeforces
Codeforces divides its rounds by rating band, and the band decides whether a contest is rated for a particular account. Div. 1 rounds are rated for users with a rating of 1900 or higher. Div. 3 rounds are rated for all users with a rating of 1599 or lower, and Div. 4 rounds for users below 1400 or for newcomers who are unrated. Open rounds are rated for everyone regardless of standing.
Below the 1600 line the participant holds a choice. If a rating is less than 1600, or the account is a newcomer without one, the round can be joined rated or unrated. Joining rated puts the result into the standing and the rating; joining unrated keeps the practice without the consequence. Only trusted participants of the fourth division appear in the official standings table, which is the platform's own filter on whose result counts.
Rated play is not a Codeforces invention. Mobile games run the same structure: Cookie Jam, a contest between competitors on a shared leaderboard, lets a player measure themselves against rivals week after week. The word competitors covers all of these settings, from puzzle leaderboards to rated programming rounds, and the question behind them is always the same: does this round change my standing?
Fraud checks the vendors state
Contest platforms publish their fraud checks, and the three statements are worth comparing side by side. Gleam says all of its plans come with automatic fraud detection used to invalidate cheaters, so the check is not a premium add-on. SweepWidget describes its default security level as advanced device fingerprint technology verifying more than 50 data points. Woobox addresses voting fraud directly: its vote export flags a vote that came from an IP address already known in its system as a fraudulent source, and that vote has already been blocked.
For an organiser, the comparison is about where the burden sits. One vendor puts detection in every plan automatically, one makes fingerprint verification the default, and one surfaces flagged votes in the export for the organiser to act on. Three vendors, three different places to look before trusting a result.
- Gleam: automatic fraud detection ships on every plan and invalidates cheating entries.
- SweepWidget: device fingerprinting verifying more than 50 data points is the default setting.
- Woobox: flagged IP addresses lead to blocked votes, recorded in the vote export.
Where the mechanics stop
State the limits plainly. Facebook offers no route to edit, appeal or contest a posted Marketplace review; deletion is the whole toolkit, and it forecloses a second review. LeetCode's documentation describes how a rating is calculated but not a formal appeal against one. Codeforces states which rounds are rated for which bands, yet the entry rules do not spell out how a disputed result is reviewed.
Platform rules decide, and the organiser's checklist ends where the platform's help pages end. A buyer weighing a review, a participant reading a rating, and an organiser comparing fraud checks all read the same kind of sentence: what the platform does, stated by the platform. Anything beyond that is guesswork dressed as guidance, and this reference leaves it there.
- No edit, no appeal: the review stays as posted until deleted.
- Rating arithmetic is published; rating appeals are not.
- Divisions fix rated status in advance; disputed results have no stated procedure.
| Platform | Stated control | Stated check or limit |
|---|---|---|
| Facebook Marketplace | Deletion only, no edit or appeal | Seller reviews are app-only |
| LeetCode | Contest Rating shown on the profile | Ranking uses score and finish time |
| Codeforces | Rated or unrated choice below 1600 | Division decides rated eligibility |
| Gleam | Automatic fraud detection on all plans | Cheating entries invalidated |
| SweepWidget | Default security level | Fingerprinting verifies 50+ data points |
| Woobox | Vote export flags suspect votes | Fraudulent-source IP addresses blocked |
Procedure
-
Open the app
Seller reviews exist only in the Facebook app for iPhone or Android, so start there; a computer or a mobile browser cannot post, manage or delete one.
-
Find your review
Go to the seller's profile in Marketplace and locate the review you posted for that transaction, since the review, the seller's reply and the deletion control all live in the same place.
-
Delete with the trade-off in mind
Deleting works at any time, but a deleted review cannot be posted again for the same transaction, before or after the seller replies. Weigh the wording once, then decide.
Readers ask
Can you contest Facebook Marketplace reviews?
No. Facebook provides no edit function and no appeal process for a posted seller review, and the review becomes public the moment it is posted. The single control the platform documents is deletion, available at any time. A deleted review cannot be replaced: once it is gone, no second review of the same seller for the same transaction can be posted, so the wording deserves care before publication rather than afterwards.
How to know your LeetCode contest rating?
Open the contest profile on LeetCode: the Contest Rating figure and the Attended count are shown there. Ranking inside a contest is decided by score and finish time, with fewer mistakes rewarded, and LeetCode has stated that every contest season shares the same rating algorithm, which is what keeps the figure comparable across seasons and between accounts.
How do you know if a contest is rated on Codeforces?
Check the round's division before joining. Div. 1 rounds are rated for users with a rating of 1900 or higher, Div. 3 rounds for users at 1599 or lower, and Div. 4 rounds for users below 1400 or for newcomers. Open rounds are rated for everyone. Below the 1600 line a participant may choose rated or unrated participation.
Can a seller reply to a Marketplace review?
Yes. Facebook's own help text refers to a seller replying to a review, whether the reply comes before or after the buyer deletes it, so replies exist as the seller's side of the exchange. The buyer's controls remain deletion only, and a deleted review still cannot be posted again for the same transaction.
Do contest platforms detect fraudulent votes?
Yes, and each vendor describes the check differently. Gleam says every plan includes automatic fraud detection that invalidates cheating entries. SweepWidget's default security level verifies more than 50 data points using device fingerprinting. Woobox says its vote export flags a vote from an IP address already known in its system as a fraudulent source, and that such votes are blocked.
Can a buyer post seller reviews from a computer?
No. Facebook states that seller reviews are only available in the Facebook app for iPhone or Android, and that buyer and seller ratings cannot be provided from a computer, a mobile browser, or Facebook Lite. Anyone planning to leave feedback after a Marketplace transaction needs the app installed first.

ContestsOnline does not sell reviews, votes or ratings, and it cannot restore or remove a Facebook Marketplace review for anyone. This reference is not legal advice; a lawyer should be consulted where a dispute turns on defamation or consumer law. The site never teaches vote manipulation, and no organiser or platform guarantees an outcome.
Woobox's user terms require entrants to agree to the organiser's official rules, so any limit on bought or incentivised votes depends on the particular contest. Walmart's Associate Talent Search rules prohibit paying for votes and let Walmart void fraudulent votes or disqualify the entrant. The platform's terms and the organiser's rules are two documents, and a disqualification is decided under the second.
Woobox lists three warning signs of bought votes: many votes from one IP address, votes from people in different countries and regular voting intervals. Award Force says its platform detects and blocks automated or scripted voting and rate-limits rapid voting. Ordinary participation is uneven in time and independent in origin, so it shows none of those patterns; this describes how checks read a count and is not a method for passing one.
In the United States, the FTC says a sweepstakes cannot require a purchase to enter, and California says a sweepstakes must offer a way to enter without cost. Those rules concern sweepstakes entry, not votes: whether a contest allows paid votes is written in its own rules, and ViralSweep even lets organisers configure Pay to Vote. Contests whose rules bar outside votes are refused, and so are political ballots.
Once voting closes, a refund applies where votes ordered for a contest never appear in the count the contest itself displays. ViralSweep says its protections may silently flag and block a vote, and Woobox says votes from IP addresses it has flagged as fraudulent do not count even when the voter appears to have succeeded, so the displayed count is the test. An organiser's ruling or a disqualification is never refunded, and neither is an account ban such as the permanent one Gleam says a breach of its terms may bring.
