These bounty hunters still keep to amaze me... I mean 100% of this guy's post history (2k+ posts)  consists of "proof of authentication" and "bounty report" kind of work, and he thought that no one will notice this sudden change in the behaviour. Actually, he probably didn't even try to think about it, which then resulted in this blatant example of chatgpt spammer.
