I have located some ''search'' articles on their site before; and recently (can't remember the term I was searching) ran across a response that stated that there were no more edits from unknown sources being accepted for that particular entry.
I believe the original premise of having a site that was like an encyclopedia, but with the option of ''editing'' being left to pretty much everyone viewing the site/entry, was an interesting and helpful idea. HOWEVER, as with all good ideas, there entered some roadblocks, etc.

From Wikipedia, the free encyclopedia
Welcome to Wikipedia, the free encyclopedia that anyone can edit.
In this English version, started in 2001, we are currently working on 970,053 articles.
If you click on the ''anyone can edit'' link, you get this: http://en.wikipedia.org/wiki/Wikipedia:Introduction What is Wikipedia?
Wikipedia is an encyclopedia written collaboratively by many of its readers. Lots of people are constantly improving Wikipedia, making thousands of changes an hour, all of which are recorded on article histories and recent changes. Inappropriate changes are usually removed quickly
On that same page is a link regarding ''vandalism,'' which states: http://en.wikipedia.org/wiki/Wikipedia:Vandalism
Vandalism is any addition, deletion, or change to content made in a deliberate attempt to reduce the quality of the encyclopedia. The most common type of vandalism is the replacement of existing text with obscenities, page blanking, or the insertion of bad jokes or other nonsense.
Any good-faith effort to improve the encyclopedia, even if misguided or ill-considered, is not vandalism. Apparent bad-faith edits that do not make their bad-faith nature inarguably explicit are not considered vandalism at Wikipedia. For example, adding an opinion once is not vandalism -- it's just not helpful, and should be removed or restated.
Committing vandalism is a violation of the Wikipedia policy; it needs to be spotted, and then dealt with ? if you cannot deal with it yourself, you can seek help from others.
A 2002 study by IBM found that most vandalism on the English Wikipedia is reverted within five minutes (see official results); however, vandals persist as a problem for all users, and it is a good idea when editing an article to check its recent history to see if recent vandalism has gone unnoticed ? even if the last update was more than five minutes prior.
Not all vandalism is blatant, nor are all massive or controversial changes vandalism: Careful attention needs to be given to whether the new data or information is right or whether it is vandalism.
It appears they are trying diligently to avoid scandals and such, but there are the occasions where an ''edit'' may be retrieved and shared throughout the WWW prior to it being truly edited and corrected by the site coordinators.
Kinda makes one wish they were in there so they could change things.
