It's my opinion that he means well. That he gets a sense of belonging and support from the BITOG community. He has been a prolific poster, including video, and he keeps returning because of that positive feedback. Sure, there's been negative feedback, but in general, folks here have been willing to respond, and to try and help.
I don't believe that he is trying to upset folks, to troll the forum. The fact that he manages to upset folks is simply incidental to his intended result...
