Steve, most of your posts on this site are in the off-topic areas such as this thread. I don't know the specifics but I'm sure if you even out the ratios a little the six-minute limitation will go away. RCG has a number of built-in blocks to prevent robots from posting huge masses of spam here, or just to prevent general trolling. Nobody can make exact duplicate posts within like five minutes of each other, for example, and there's a max of one post report per minute.
As for Cullen, what did him in was his correspondence with JTG regarding the closure of the Hillbilly thread. He made a few unfounded accusatory remarks about RCG moderation and said something about not wanting to use the site anymore. Jim is perfectly happy to close ANY account ANY time for ANY reason he deems valid regardless of what the rules say, and like it or not he can do as he pleases. He banned Will Haney a few years back "for being Will Haney"
If you want more details (some true, some not) about RCG moderation, there's another site you can peruse. I think its name is still censored on RCG: ... Yep. Won't let me post it.
