That was i was told to provide my complaint with BTC address linked to my account i claim got hacked and sign message, or from a post i made with bitcoinadress in from that i can sign to proof that it is my account...when someone can help out that would be wonderful.
Further i never had posted any bitcoinadress besides in my signature and that got changed.

Besides what provided above and provided actually a solution i have no other proof. Unfortunately that all is called out as " everyone can come and claim accounts", so who i am even addressing my hacked account.

Fact is that i informed bitcointalk about the hacked account when i found out that something must be wrong immediately 4th of january. because i didn't login for several month there is a period with no posts from September to January as i wasn't in the country and had no internet. somehow down the line the hacker started to use one week after to post on this account whereas the account should have been blocked the moment i adressed it. This means it must have happened somewhere in early new year or late last year.

This raises the questions how much more accounts got hacked and compromised or even was there another data leak from bitcointalk which we don't know yet. I mean it happened before.

This whole issue leaves for me a bad taste on this forum as simply telling me no signed address no account back and that i might get treated different when i purchase a membership. All i ask is to block the account until its sorted. Personally its a big issue someone running around using other peoples account by compromising them.
 
Still 100$ in BTC bounty to provide details and who it was so i can take the corrective measures from my end. Again thank to bitfort who pumped me over and started the discussion for me.
