Re: Master-P POSSIBLE SCAM. I lost complete faith in this forum now.
So if I steal your money, you threaten to dox me if I don't return it, and I make a post saying "Don't worry, I'm working on it, and, BTW, this is really me!" you wouldn't dox me?
In such case, yes, I would reveal personal information so nobody would deal with that person again, as that person would most likely scam again (or would at least stop scamming now that their personal information is known). But that's not the case we're seeing here neither what you propose would really help right now.
Not sure I understand your ELI5. Please tell me which number you disagree with:
1) TECHSHARE threatened to dox Master-P if money is not returned.
2) Master-P (real or not) makes a post, 'proving' that he is, indeed, Master-P.
3) TECHSHARE, satisfied, agrees to stop (postpone) the doxxening.
4) No money changed hands.
No one will hurt you bro. 
I'm certain of that. Even if I stole everything you owned, shat on your bed & raped your dog.Source: Entire history of this forum.
