Wikipedia is considering implementing a 'Flagged Revisions' system, under which information posted by non-established users is checked before being made publically available.

The decision by the site's owner, the Wikimedia Foundation, comes after it was revealed that on several occasions incorrect information has been posted to the online encyclopedia.

The Flagged Revision system has already been trialled on the German version of the site and see those regular contributors, who are considered reliable, allowed to make changes which are instantly visible on the site. These contributors will also be responsible from checking changes made by less-frequent contributors.

The site's co-founder Jimmy Wales said the move comes after a number of people had posted incorrect information about the death of two US senators.

"This nonsense would have been 100 percent prevented by Flagged Revisions," he said on his talk page.

Wales did, however, admit there were some problems with the system, in terms of the time taken to approve changes. During the German trial one amendment took three weeks to be approved.

"They have an approval delay of three weeks at times, a figure which I regard as unacceptable. Our version should show very minimal delays (less than one week, hopefully a lot less) because we will only be using it on a subset of articles, the boundaries of which can be adjusted over time to manage the backlog," he said.

Wales claims that a Wikipedia community poll, which took place earlier this month, shows 60 percent of users are in favour of the Flagged Revisions system. However the proposal has been met by much critisisim from Wikipedia users.

"How exactly do flagged revisions do anything to end the problem of unreferenced or poorly referenced BLP's [biographies of a living person]? Even now these problem BLP's are still being created," said one Wikipedia user.

Wales responded to critics of the system by asking for alternative suggestions.

"Those who are in the minority who are opposed to this are invited to make an alternative proposal within the next 7 days, to be voted upon for the next 14 days after that, a proposal which is clearly aware that you are in the minority and that does not attempt to simply re-hold the same vote," he said.
