I don't have merits to give anymore but I left him positive feedback
I suggest you to reconsider your feedback, I would say neutral feedback is more appropriate in this case.
I think I
disagree with you on this;
I'm with Helena on this one: catching a cheater doesn't mean the user can be trusted. There was no amount risked.
The user who bursted the double signature scammer, I merited that post on Duelbits thread and also left s/he a positive feedback.
As Royse777 made an update on BetterCallRaul thread, I discovered that someone I barely gave a +ve feedback for bursting a scammer is accused of using AI to make posts.
I just quickly changed the +ve feedback to neutral while capturing the AI incident.
