Find me a Bitcoin address I've used on this account whatsoever and i'll sign it : )

I just went through your posts, and I cannot find a Bitcoin address. Am I missing something?

maybe that was the trick he doesnt have one so he cant do it

That is what I was wondering, but Im not going to accuse him of stealing it till proper evidence is found.

how can anyone actually find out if the account was hacked or not?

If he can't sign a message from an earlier address (He did have an altcoin addy he could sign).
