Kindly, note that LocalBitcoins do not remove or edit feedback, unless it contains abusive, racist language, threat or exposes personal information.
Each user can give one feedback to another user. Possible feedback options are: Trust, Positive, Neutral, Block and Block without feedback. Positive and Block requires at least one common trade between users.
Feedback is considered confirmed when one of these conditions apply:
Trade amount between users is more than 0.5
Total trade volume of feedback leaver is more than 50
Feedback leaver has verified ID
When feedback is confirmed, it affects the feedback score of the targeted user. When feedback is unconfirmed, it is kept hidden from other users. Only receiving user and admins can see it. Unconfirmed feedback doesn't affect the feedback score.
Users that never had trades can't leave feedback to each other, however they can add one another to "Trusted list" or "Not trusted list"
