As far as i know there is no difference between an automatic submitted backlink and a manual submitted backlink. But as far as i know it´s not possible to post with Xrumer and Co to many high PR forums. So the forums that aren´t "victims" of Xrumer will have way less outgoing links. Is the conclusion now that forums with less outgoing links are way better? Or is this already in the PR more or less included if there are a lot of spam outgoing Links on the domain? Thanks!
