Yeah, could you link me a list of accounts that have been recovered over the past 10 days? Fuck me, link me to the list of accounts that have been recovered over the past 2 months. What makes you think OP's an exceptional case that his account will be recovered on a priority basis?
Please quote where in my post I said that OP's case is either: a priority; going to be solved quickly; going to be solved at all.
If you want us to recover a hacked/lost account, you need to prove that you own it. Typically, the only acceptable method of proving ownership is by signing a message (including current date and desired new email address) using a Bitcoin address or PGP key associated with the account. A Bitcoin address or PGP key is associated with the account only if the account posted the key/address, sent it in a PM, or if it is still listed in the account's profile.
I very rarely recover accounts if you can't prove ownership as described above. There are alternative ways of proving ownership, but they take too much time.
Safe to assume signed message from an ETH address would be considered as an alternative way of proving ownership?
Again, you don't know. Nowhere in his post - or anywhere else (still waiting for pugman's source) -, he says that ETH signed addresses aren't accepted. Either OP can post his signed message and keep bumping it every couple of days/weeks or he can just give up and create a new account/leave the forum. Either way, he has nothing to lose.
