It makes it much more expensive to link farm (since they have to make ~50 good edits before changes appear, which costs *time* and hence (for a company) *money*).

Judging by comments on SEO and webmaster froums there are already people who will make a number of good edits in order to get their link in. The general opinion appears to be that we are pretty good at removeing spam links.
