Personally, I find this sort of phenomenon informative. The shield of anonymity protects trollish, hostile, or potentially psychologically unhinged posters from the bright light of community scrutiny and other appropriate action so it may at times indeed be necessary for a moderator (Rob, in this case) to remove their posts when they wax slanderous or threatening. As long as they are simply educating the community regarding
diversity by demonstrating divergent opinion (and, perhaps inadvertently, by showing how far out there the fringes of the bell-shaped curve may extend) though, then I'd let them run their course as long as doing so is not creating a legal liability or potential for real damage to someone.
For example, if a poster rants that a Punawebber living at [address] and working at [name of company] is a censoring fascist on a power trip, regularly beats his wife, molests his pets, and sells substandard widgets then I'd recommend at least deleting the home address and the name of the company, if not the whole thread. Real names, likewise, since those will pull up in a Google search (which is why I am AlohaSteven online instead of using my legal name) by grant reviewers or potential employers. How much time can Rob or anybody else devote to policing such a volunteer community forum, after all? If this was Facebook (gawd forbid!) then paid minions could be the censoring fascists on power trips, but not so here.
If, however, a poster has already been banned from a forum and is attempting to sneak back in, then the rules already deal with that scenario. How sad, though, for someone to spend time & energy fuming and wanting back into a forum s/he reviles. Do move on to happier and healthier pursuits, I'd suggest; life is too short to stay mad about either real or perceived slights.
