Well, as to the pedophile thing, DR was continually pointing out that by constantly (and it was near constant) trying to derail and disrupt the discussions about major pedophile arrests/news, @wAcKy ZeBrA was tacitly defending pedophiles/evil. I never once saw him accuse anyone of being a pedophile. There are dozens of examples of him saying that.
As for the PM nonsense that @wAcKy ZeBrA dragged you into, obviously I have no idea what was said, but I can say that DR absolutely denies calling him a pedophile there either. And yes, I do have DR's email address, and I did talk to Greg post-ban.
1.) Tell them what you and your mods traditionally tell most others that complain about PPP: You're on your own in PPP, use the ignore function.
2.) Did you go through it with DR? I guarantee you that he could have explained himself, and damn sure bet he would have been receptive to correction if you felt he was crossing a poorly-explained line.
3.) I don't disagree with what you're saying, however, had you bothered to do more than a cursory review (which, I get, you have limited time - and certainly it's unreasonable to expect you to go through tens of thousands of posts), these same whiners flung far more vitriol at DR than he did at them. Virtually all of it unprovoked. As others have repeatedly said about him, he was very patient with other posters, until the point it was clear that they were just trolling.
If you want to change the rules, that's your right. This is your site; you're the king. All I ask is to please just make it clear what is and what is not acceptable before just telling people they're not welcome in your community.
Edit: And Scott, please do not read into this that I'm trying to crap on you, or that I don't appreciate the community here that you founded.
