I don't think he is. Pinkman12345 has a post gap like Chevas and I think it was a bought account. I have some info which might release his doxx if proper proof is there and is reported.
Engg. Chakks is a kind of person who finds his scams as kind of trophies and I think some of his scams previously had his alts involved on both side to make a fake accusation.
After I posted on this thread I saw some changes in the real guy's social and chatting accounts. So I think this might be it. He also blocked me on telegram when I asked for for response on this matter.
