It's probably this case from October that was recently bumped: harizen - ban appeal. But the OP of that thread seems to have given up and hasn't been online for months. He can't expect other forum members to fight his battles if he isn't here himself anymore.

I don't think the forum has an existential problem with account hacking and people left and right losing access to their accounts due to no mistakes of their own. If that was the case, we would see dozens of complaints weekly. We get a few complaints every now and then and it's unfortunate. Although we never understand what exactly happened, it's usually a mistake of the user. Some don't want to admit it, others don't know what they did wrong. But remember, prisons are full of people and they are all innocent if you ask them. I am not blaming anyone, just saying.
