I think the problem is that the tipster was not an anonymous do-gooding citizen. I don't know the exact sequence of events, and I don't want to overstretch the analogy, but if a policeman happens on a bar fight, and breaks it up and sends both patrons home with a warning, he might be dubious when, the next morning, one patron calls him to report the other patron as having committed a crime. And it would hurt his cause even more if he followed the policeman's girlfriend home and made annoying phone calls to her.
Well, like you say, you don't know the exact sequence of events...
Two things here: First, Bagley has always maintained that he felt he was "doing Wikipedia a favor" when he reported that Mantanmoreland was likely to be Weiss, and that he actually thought someone would say "thanks for the heads-up!" or something to that effect. (You can ask him...)
Second, Bagley, and to a lesser extent Byrne as well, have since maintained that they're not all that interested in being "Wikipedians" and would, indeed, leave the site forever - I vaguely recall the term "in a heartbeat" being used at one point -
if they thought they could trust the WP'ers left behind to keep Weiss's activities under control. Some Wikipedians supposedly tried to give them that assurance in the Mantanmoreland ArbCom base, as I recall - but the fact is, they
can't keep Weiss's activities under control, couldn't even if they wanted to, because
Wikipedia simply does not have effective preventative measures in place against abusive editing - other than page protection, which can just as easily be used to prevent ameliorative or corrective editing.
Meanwhile, Weiss has steadfastly refused to admit that he's ever edited Wikipedia at all. At this point, I (for one) don't believe a word he says about anything, including the notion that he wants to protect us all from the evil right-wing agenda, or that Byrne is some sort of terrible businessman.
