Yeah, I'm really surprised. I have no explanation for that but my account is NOT for sale! And I changed the password a few minutes ago.
How can I find out wheter I got hacked? I don't have these messages in the outbox, I haven't even used this account for weeks...
What a coincidence

I hope you understand that this is hard to believe.. especially since you didn't post in the last ~8 months and coincidentally came online yesterday

I don't see a way you can proof this certainly wasn't you or someone you tasked with selling your account.
A signed message only shows that this is really you at the moment.
And IP logs only show whether you used the same IP to log in. This doesn't say anything about someone you tasked with selling your account or a VPN / proxy you might have used.
I dont think he needs to prove his innocence. The OP needs to prove guilt. He can report the PMs to a moderator who can authenticate the PMs.
It is trivial to fake a screenshot....they have been faked in the past few months.
I think i have shown enough proof.
It is quite amusing how you (as an account farmer) are trying to protect account seller with every possible way.
Maybe @TrustedAccSeller is your seller / buyer ?
Or is it simply you ?
If bob123 gives me access to his throw away account
alice321, I'll confirm the PM (if it's there

).
Done.
I have send LoyceV a message containing the login credentials. He can verify the messages.
