But the recovery process will be much longer or forever
I think soon there will be a solution because everyone is fed up with this. I have seen somewhere theymos said he is willing to spend $100k for solving this problem. Also, here is a statement from hilari-
You should probably just wait and hope that theymos implements the automatic recovery tool which he said should be ready by the end of the year, because your account just realistically isn't going to be recovered otherwise unless cyrus mysteriously starts to restore them or more staff are given access to do so.
so you can ask any of the DT member to tag that account until you recover it.
Without strong proof that OP is the actual owner, I don't think DT will tag the account. Also, DT should not tag, IMO.
@OP
As per the rules of recovering account, you don't have any proof that you own the account. The possibilty of recovering the account near zero almost.
Anyway, I wish any trusted old member can verify the real owner in different ways so that you can get back your account. Good luck.
