Trading with TOAA is high risk, a very high risk of losing your sanity. Also newbies wont look at neutral feedback, they probably dont even read positive trust half the time
I wouldn't trade either with him anything.
And newbies just maybe look at the Feedback when the boards show the trust score.
Most times they read the Feedback after they have done something with Users i guess.
For sure not all but still a few doing that.
Happend to me when i was starting here on Bitcointalk.
