Can Wikipedia withstand the weight of spam?
Will Wikipedia face the same fate of the Open Directory Project -- where marketeers have spammed the site to render it useless. That's the view of Law professor Eric Goldman in a recent blog post in which he predicts the site's demise by 2010 unless it fundamentally changes its editorial process to become much less open.
Goldman writes:
As Wikipedia traffic grows, it becomes a juicier target for marketers seeking to promote themselves... Wikipedians are the only thing stopping those marketers from modifying Wikipedia's open-access pages in ways that might degrade the user experience. Wikipedians, in turn, will fight the marketers because of their pride in the site. However, as marketers become more determined and use automated tools to mount their attacks, Wikipedians will progressively find themselves spending more time combating the marketers.
Meanwhile, Search Engine Journal is reporting on a recent change made by Wikipedia which will help to combat spammers who add links to the site in the hope of increasing their page-rank:
As of now are all outbound links from the english Wikipedia Site using the NOFOLLOW attribute, no exceptions.
No matter where you place it, Article Page, Talk Page, User Page, Project Page, whatever. No Link will get any credit at the major search engines.
This will not eliminate SPAM at Wikipedia, but it will over time certainly reduce it a bit. Especially the spam of invisible pages that have virtually no traffic but at least some PageRank is now virtually a waste of time for any spammer.
