Yes It was hacked
Hou can I make a sign message?
I never seen this before, a Hero Member asking about how to do a sign message?
Did you buy this account or what?
But however, you don't need to be shy to ask something
I would agree it's kinda hard to believe a Hero who has not had to sign a message. I supose it's possible but in that amount of time... most have had to sign something. Even if you have not had to sign something you have went through Meta where it is happening all the time.
So I think most true hero members would have seen it. The hard part is even if he/she bought.... it is allowed. I don't really like people buying accounts as I put so much time into mine.... but people are allowed to do it on this forum. So even if they did... they still are able to get it back, assuming they learn to sign message and prove ownership.
