I don't have any BTC address or PGP key associated with that bitcointalk account. Honestly this is the only platform in the world where you can change password and email without an email confirmation, so you should do something about that because you can't secure you account enough. Of course that first of all it is my fault, but you also should do something about those confirmations. I provided a lot of evidence which proves that account it is mine, so if you don't want to restore the account, on the email it was since I created it until today when it was hacked, it is because you don't want to that, you have enough proves. Honestly why I would lose time to steal that account, it is a poor Jr. Member, but for me it is important because I built trust upon that account and now I have to do that again on other account in order to get accepted to translate new projects.
I can tell you what PM I sent or received in the whole history of that account, what bigger proof than that could be ?
In 1-2 hours I will get back home and I will try to make again that signed message for ethereum.
