But what happen if the seller take back his account by proving the ownership of old address after sell the account to someone? Is it still possible right?

Please respond, I'm curious about this one.

No need to worry if the buyer have signed message from the seller when buying accounts, that would serve as proof of account transfer and he cant claim it back

Well when you buy an account you ask the seller to sign a message that that account is sold to you, and you must keep this message for future, so you are protected. - my opinion

its not just your opinion, i agree with it as well. by stating in the signed message that the account will be sold to you, the seller can no longer claim the account back as theirs using a signed message.

Quick question about signed messages: Now, from what I understand, for a signed message to be valid, it must have been fron an address associated to the account from a post or something at some point. If a person were to purchase an account, and then decide to resell it for whatever reason, how could he legitimately prove ownership without having access to an address that has been associated with the account for an extended period of time?

The buyer can't proof that he is the legitimate buyer except he got a signature from seller that says that the previous owner sold the account to him. The new owner should have posted a bitcoin address so that he can proof, with another signature, that he held the account since then.

When selling an account then the message should contain the date of sale, the account to be sold and the buyer who bought it.

I agree with you, a date should be included in the signed message, i dont know if we can verify when has been signed the message can we?

if a date is included in the signed message, that should be sufficient proof the message was signed on that day if the message can be verified as valid; the signature for the message wouldnt be valid if any part of the message or signature were to be changed.

Yes i know that, but i was wondering if we can verify when was that message signed if there is no date in the message.

yes, the signature of the signed message is only valid for that particular message. the date is just a part of the message. if the signature corresponds to the message it should be verifiable without issues.

I think he is meaning something else like: The signed message "xxxx and address xxxx and signature xxxx" has been signed on Tuesday 21 July 2015. If i understand his question
