@mamiakimo - sorry to hear about your plight :( Until we get some official guidelines from Google relating directly to this specific UGC/forum hit (around nov 12) nothing we can say is guaranteed to help.
In all the responses I've got on this subject from webmasters, none speak of a real recovery from it. Traffic seemed to decline since then.
It has (based on our naturally restricted viewpoint) hit somewhat randomly. It didn't seem to favour one forum over any other for any specific reason. Though it could have hit us all 'equally', impossible to say without having Google's data on this.
It's also got messed up and tangled with the Panda updates, but most of the people I spoke to benefitted from Panda.
I'm working to get some more meaningful dialogue (in general) from Google. I'm nobody special, but I'm going to try. Wish me luck.
