This user does not seem to be trustworthy. He has sold an account to another user but used it to send out messages begging for BTC to random users on bitcointalk prior to delivering the credentials to the new owner. If you were to deal with this user I would highly recommend using an escrow, and possibly avoid account trading with this user completely. See reference link for more information.
Since he is no longer in DT it got hidden and alongside lolxxxx should be given a negative trust because he is quietly participating in signature campaign with his neutral account. Also complain this to the campaign manager.
In addition to this there is one more alt account found:
