I think there's a few reasons why people should be laying off bungle, but I don't think that necessarily means that all of the heat he's taken has been a "feeding frenzy", "ganging up", or any of those other terms. Sometimes, posters succeeding in so badly pissing off so many people that it is understandable, if not necessarily fair, that they decide to give as good as they get. And sometimes, people might feel they want to support or defend their friends if they've been getting grief from the poster in question.
So, even if discretion might now be the better part of valour - it's pretty obvious that Bungle is struggling to hold it together, and I don't suppose any of us want to be the one who actually pushes him over the edge - I think it's inaccurate and unfair to start characterising the situation as one in which people have been ripping in to him for no good reason at all, by using terms like "feeding frenzy".
As I've said, I'm not whiter than white on this matter, but I have watched Bungle's responses with increasing dismay, and I think that there needs to be some kind of way of bringing the situation to an end before it goes badly awry.
Perhaps this is the point where people should be posting pictures of fish?
