articus, URI93 is right. These jerks are posting crap all over Yedda, probably because they know they can get away with it right now because nothing is working properly to report them. But when you do see things like this, report it and yedda will remove them, however like URI said, Yedda will delete them, but they'll be back with another screen name.
With all their new formatting it's too bad the staff can't come up with a way to eliminate them permanently or fine them for using unauthorized space to advertize. Oh well. Just report them whenever you see them. (when you can again of course.)
