Suggestion: Scam score based on a screenshots proof, approved by the arbitrators
**Idea on a reputation (scam score) system using real proof/screenshots approved by arbitrators:**

After a few months from completing reversible payment method trade, money are charge back by a scammer. Victim makes a screenshot proof of the chargeback and also of the initial incoming transaction. Victim finds a scamming trade party in a Haveno trading history and submits a feedback/review along with that screenshots to the community arbitrators.

**Arbitration process:**
If arbitrator dismiss the submission, one more arbitrator needs to confirm the decision (a mechanism against biased arbitrator where can be seen identity of the previous arbitrator?). The screenshots of the scam are presented in a non downloadable and temporary form for privacy. Arbitrators can easily use magnifier to verify screenshots quality and can ask for a new/better screenshot maybe.
**Protection of the feedback arbitration system from misuse:**
1. submitter can only post a feedback on someone if there is a completed/closed trade with that person and if he never submit the feedback request for that person before
2. feedback is dismissed on the poster and arbitrator side(because poster can adjust software) in case the submitter caused two dismissed feedback in last 30 days.
3. arbitration system does not accept/dismiss the feedback request if there is lets say 2 feedback requests open for same submitter.

**Displaying scam score/feedback:**
Approved feedback is visible for anyone under scammer profile, for example "Scammer: 1 case (last: 2024-12-06. 18 fiat trades since then.)". Visitor can click number of cases and see the feedback of the victims. If indefinitely storing feedback is not ideal, maybe showing the number of approved scam cases is enough.

**Block trade offers of a scammers:**
Maybe Haveno should deny submitting new fiat trade offers of the users with 3 scam cases or more and also if scammer modify the software to submit it anyway (if that is possible), other users should not see offers of such scammer. This should be done only if the feedback arbitration system is bulletproof and false feedback can not go through/approved.
Maybe add a setting enabled by default to hide trade offers of people with X verified scam cases.
