xfire ads box

instead of having huge amount of "i'm cless"/"need moviemaker"/"avi to make movie"/"need logo" journals or forum topics in which nothing really important is commented (usually its just useless gl stuff), i think xfire would benefit from ads box below forums box in which that kind of spam journals/topics can be posted so it doesnt push down topics that actually contribute to site or community.
ether that or make some kind of extra filter called "crap" for example and make it possible for admins to flag such journals and topics as crap so they get filtered out. thx, luv you all
