NoFollow – not for wikis?
1. Wiki spam won’t stop because spam is already removed from actively maintained wikis. Still we get spam. Why? Because spammers will continue to spam as long as they find the occasional unmaintained wiki. Wiki spam will only stop after a very very large majority of all existing wikis, maintained or not, supports NoFollow. Basically this is not a good strategy. We need to find a solution that protects *unused* wikis from spam.
2. Even if we “whitelist” some sites using InterLinks we loose a lot – unpopular sites will not rise in pagerank due to wikis, because it will be to much of a bother to create a LocalName or an entry on the InterMap for fringe sites.
3. This works much better for blogs where articles themselves are “cleared” and only comments are “from the unwashed masses.” On a wiki this is much harder to get right. We could try keeping track of what link where added by registered users and what links by anonymous users were “approved” by registered users because they survived a page-edit by a registered user.
