seems like just that, oh wait that MUST be proof it was him then, if you are going to which hunt just get real proof, server logs, domain registrar emails, email trail, something, its really not an unfair thing to ask for ... proof.
This is not a courtroom you muppet. We don't need to prove anything else than you being a shill or a sock for allcryptocoins, hence your word is worth absolutely nothing.
Now whether allcryptocoins hacked something or not - that's another story, and one for proper authorities to take care of. Not some random forum thread with some random sockpuppets showing up on cue.
