The account could possibly be hacked. I would not accept this account under any circumstances unless they can validate a signed message from at least 3-6 months prior to this post. This could end up to the buyer of being a stolen account. At least give it a day or 2 to see what's going on with MrTwelve. He did have a issue with a order he placed through this user.
Ohhh !, Thanks for the warning of both you ! I just have checked his untrusted feedback. Within less than a month, he had 3 deals with "red-words"
of @mtwelve , @Moderated and @Dangc . it's hard to believe a man whose his deal history is not good
