Since konungbarber issue or problem got resolved then inform him that he should clear out that scam accusation for your trust rating would be neutralize and regain back your reputation.
Not sure if it is as easy as that. I don't support nor oppose the flag, but i still find what p2pb2b did highly untrustworthy, whether or not they resolved the situation and made the victim whole or not.
I guess a Type-1 flag would suffice for that though.
I'm actually not sure what the rules regarding this are. Is the victim required to remove the flag if he's made whole? I guess so?
