London: Now anonymous users will not be able to make editorial changes to the Wikipedia pages of US presidential candidate Mitt Romney.
The pages belonging to the former Massachusetts governor and other members of the Republican Party who may run alongside him have been locked down.
The measures were taken after comedian Stephen Colbert suggested on an American television show that viewers should edit the pages, the BBC reports.
Colbert was following up on earlier media reports suggesting that the popularity of election candidates could be determined by the number of edits their entries on Wikipedia had received.
As a result, more people began editing the politicians' pages.
According to the report, the pages are now partly locked, meaning that anonymous users and those without a Wikipedia account are currently unable to make changes to the pages of Romney, Senators Rob Portman and Marco Rubio, Governor Chris Christie and others.
