although i’m new to this i think the difference between PV and SJ is one of mentality.
PV seems to have a core of good people who know a bit about each other and are polite and respectful and don’t engage as freely in offensive exchanges or respond to childish posts in a childish way. I think the moderators play a very importaint role too keeping it civil and giving advise about appropriate threads of conversation.
Suffice to say like mind people tend to seek company together and it is reasonable to assume that if the ‘wrong’ kind of poster was eather fed (as a troll) or found a small network of reinforcement within the PV forum and/or was tollerated by the moderators and members they would quite happily post shit here all day long.
