He's denying that he's hacked any of the account he's sold or that he's committed any of the activities he admitted to earlier. So he's either a) hacking accounts, selling them, and lying about it, or b) he's lying about the nature of his sales and trolling the board to make himself think he's awesome (his stated reason for doing so). He's being dishonest either way.
Seletchi has a history of hacking. He's shown the same questionable ethics, manipulative behavior, and non-compliance here that he has elsewhere. When he was banned on another forum for exploiting, he had a similar childlike tantrum and showed the same brash arrogance toward Admin. Seletchi isn't stupid, he just can't control himself; his emotions get the best of him. He fits the textbook profile of a sociopath.
