I'm sorry, I don't recall the name anymore, but their discussion forum was closed anyway, you can't read it unless you're a member (I never was).
They essentially have two groups set up, one looks like one of those "You're the Greatest" groups with those insipid balloons and stars and spangles, and their members go forth and find the ugliest, least worthy photos they can find on Flickr, and they decide which one to gang-praise. Then they paste it with positive comments and 'awards'.
In some cases, they follow up with different members of the same group who start tearing the photo apart.
The intent is to create chaos, make the person who posted the photo angry, upset, or even delete the photo or leave Flickr entirely, or to get maximum enjoyment out of making someone feel great about their horrible photo. Evil little group, methinks.
Sorry I don't recall the name. I was looking for the forum where I first read about it, but can't find it now.
