All of the rep forums have had their issues. I still go to RG the most. Has the most information on a wide variety of reps.
RWG...complete waste of time. I remember I was selling my Gen like 06 Cousteau, asking $1750 for it...Gen movement, Zig bezel lume, double AR etc...cost a ton to get it that way.
The sale thread turned into a crap fest over the asking price and ridiculous stuff.
I withdrew the sale and went on a flame out rampage and got banned. Douchebag operation and people there. Only a couple of guys were descent. Zigmeister stopped hanging there and visiting and stuck with modding business over...too much drama.
RG has had their drama and crap also. I've been hosed and sold crap by "modders" and every trusted Rep dealer on every forum.
I've seen shady crap at all the forums though...I guess it is part of the hobby though.
Wrist check is good for PAM information.
Otherwise, I pretty much hit all of them and browse around. I've had my most success selling my stuff I didn't want anymore when wanting to do something new at RG though. More traffic and buyer's seemingly there than any place else IMO.
It's all fun and games until someone gets banned though!
