yes i dont need it anymore 

I have 3 accounts and i will post a thread stating that i want to sell it. Everyone is doing it why cant i do it.

Why send PM with proposals of selling your own account to random individuals then?
And that I agree on. Signed message from an altcoin address(since it seems you're more so heavily invested in them) will work as well

Edit: However, considering no changes in posting styles can be observed, I believe further evidence needs to be posted before tagging him.

Edit 2: At any rate, I'll be tagging the account as being sold so as to avoid further scam attempts or such by the new owner.

you are real crazy i told him i want to sell my account and its not hacked he kept on saying that its hacked he did not stop until i told him what he wanted to hear. Stupid fucker

I don't want to believe in you,I want to see the proofs that whatever you say is actually the truth.You'r a newbie account ,the person you have accused is legendary,maybe he is a scammer but unless you provide solid evidence there is not much people/DT members can do here as it makes the accusation quite baseless.I'd request you to lock the thread if you aren't planning to provide substantial proofs in the future.

Wait.Can you please upload the screen shots for the same ? That's a quite active and a legendary account,chances of it being hacked (according to leaked hashes hacks ) are low.Which account was being sold ? Do you mind linking us to that account ?
P.S.: You're buying accounts,that behavior is not encouraged around the forum.Don't be surprised if you're actually scammed next time.

you interested in my account

The post seems fake, and even if it wasn't, this is kinda the point of Bitcoin.
Just remain anonymous using pseudonyms and perform transactions in Bitcoin.
I doubt they are going to be able to dox you well enough if you use a different pseudonym for the microsoft keys related transactions, and even then I'm not sure they'll be able to know with certainty that they're suing the right person.
