Only posting the address is not gonna help I guess. You need the singed message from
Stake your Bitcoin address here topic. If you have not done it before then I am afraid your road is going to be very hard and the worse case will be losing your account for good. If you are the hacker then you can easily change the contents (including BTC address) of the above URLs. So only posting them actually do not prove that you are the real account owner.
There is nothing special about that thread. In fact, an unedited post from years ago is worth more than a recent post quoted by someone else. Even better if your old post is in a locked thread since no further risk from a hacker editing it. Any of these would do.
OP delivered the proof asked by the mods (valid signature from an address posted in a valid post). Now the ball is on their court, and im afraid the ball will stay there since they can't be bothered to speed up this process. Just another soul lost in the limbo of hacked accounts, forever bumping their own threads to no end.
