"the perl monks endured people like Intrepid, sundialsvc and others with great patience and no harm done to the community"

I'm very familiar with this situation, and you are one of the many who have kindly spent considerable time correcting their posts over the years, as you know, it makes no difference. The same garbage keeps getting posted, regardless of who addresses the situation. The assumption made is that people stick around to read the rebuttal. And to be clear, the nonsense will still be here, it just won't be displayed to non logged in users, and indexed by search engines. There's no evidence to support your claim that no harm has been done do the community, nor to refute it. Do I feel like their behaviour dragged the place down? Yes. In terms of effort wasted correcting the same nonsense again and again to no avail. A drain on the energy and time which could be better spent elsewhere. Reputation wise has the site suffered? I don't know. They have their own websites, could start a livejournal (if such a thing still exists, if not insert modern equivalent) for their LARPing or whatever crazed ramblings they want.
