I never signed any btc messages ( if you ask for it, you will be ignored since you clearly didnt read this)
There is a good chance the account you are selling is hacked if this is the case.
I would recommend against buying an account without a signed message.
There is no signed message and there is no hack, ive posted some stuff to sell months ago and reposted them just recently if the buyer wants to verify this. I own the account and from your trust rating and the many feedbacks id say your just a troll. Accusing someone of being a scammer because he doesnt have a signed message is beyond ridiculous. Get lost
