I'll take a different approach to ATPG, and list the people I think aren't scum (no way that this will come back to bite me later, no sirree):

Ishmael
Believer
Bestrfcplayer
Tratorix
Yarapolk (most questionable of this lot, I don't really know his style)

I frankly can't be bothered to trawl through the thread to find evidence to support this list, and it's based entirely on intuition anyway. I'm also not really sold on B_Ray being scummy, but I'll refrain from making any judgement at present. Finally, I don't want to touch the scan results with a ten foot stick at the moment, considering all the weird mechanisms that have been bandied about - I'll let other people analyse those.
