This thread is in the APB section and lists 4 middlemen. They are:
Ravallo, which I can't send a personal message for some reason.
Approved, whose last visitor message reads "o well thanks for scamming me. -.-". Not sure if I can trust this guy.
Symmetrical, who wrote this middleman thread, but says he doesn't do APB trades.
Color, whose display name has been changed to "****** BLUE TURD". Underneath that, in his profile, it says "COLOR SUCKS HIS MOTHER'S DICK". So, not gonna use that guy either.
Is some of this related to the recent announcement saying "our user database may have been compromised last month" and asking everyone to change their password?
