Oh, okay. That might have been slightly before my time. In any event, I agree with you, I don't condone such behavior from anyone, and would urge all CDRLab forum members not to participate in such actions.
I'm a little surprised that CDRLabs folks would do such a thing, even in retaliation, since (with a few notable exceptions - one of which, I'm sure, is still fresh in everyone's minds) CDRLabs posters seem to be quite civil. In general I think it is best to just ignore obnoxious behavior and let it naturally run out of steam.
