In my experience, it would help if you didn't accuse every new poster of being an undercover banned poster. Because, why would anyone new want to post here? The few times a new poster shows up, I've noticed, you treat them like lepers.
Nfreeman and SDS don't act like "moderators," in the true sense of the word. They tend to dictate the conversation in the way that they see fit. That's not "moderation," but they don't give a damn. Moderation allows the flow of conversation to take place within boundaries. SDS and nfreeman stick their rudders in and yank in the direction that they see fit. That's fine, as a poster, but on a board without any accessible rules of conduct, they do not make the board friendly to newcomers.
There is also a culture of hazing new posters to test their limits. It's amusing, I'm sure.
