Moderation here is fine. I have seen some where the topic got very off track ( and I saved it, and it was Australian, and I gave half of it the next day to the banned member when he was sober, not good posting when plastered) and caused a lot of friction.
There is a fine line between being too strict and not strict enough, and here it seems to be around the right level. When I ran a mailing list ( and had to approve all posts with the amount of canned mystery meat that came in) I was given both ways all the time. Kind of Sux but hey, you get a thick skin and can tell them to go sit on something and rotate, and as I knew most I could do so in person as well. Some you couldn't tell direct to their faces and expect to walk away with teeth, so there was sometimes diplomacy involved.
As to Rolandpen, there was nothing wrong with him that a few more years out in the real world, a lot of Ritalin and a straitjacket could not cure.
