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.
TECSHARE only agreed to postpone doxing Master-P because he made a post that contained a verified signed message from a previously used address. This makes it highly likely that that was the real master-p, but we do not know for sure. If he does not restore the funds within some amount of time, TECHSHARE will continue with doxing master-P.
