The disclosures were made public on the site by users updating the profiles of the four celebrities in question.
While Wikipedia’s administrators were quick to delete the references from the celebrities’ pages they remain accessible in an archive.
The married Premier League footballer who took out a super-injunction to stop details of his alleged affair with ex-Big Brother contestant Imogen Thomas came in for the most exposure with his profile updated at least 10 times with references to his supposed playing away from home.
“[He has] lost his discipline and had been playing away from home with non [sic] other than Imogen Thomas from Big Brother,” one user wrote.
An actor who obtained a super-injunction to prevent Manchester prostitute Helen Wood from going public about him allegedly paying her for sex was similarly “outed” on his profile page.
Under the charity heading of the actor’s file a user wrote that he was a “patron [of a] prostitute in the Manchester area”. Another changed his middle name to “super–injunction”.
Wikipedia said it could lock the pages to stop users from editing the celebrity profiles if needs be.
Meanwhile, BBC presenter Andrew Marr has been criticised in Parliament for using licence fee payers’ money to secure an injunction banning details of his extra-marital affair being published.
The senior journalist, who is paid £600,000 (€675,000) a year by the corporation, used his private cash to take out a gagging order and keep secret his cheating.
He was branded a hypocrite this week after abandoning attempts to hush-up the affair, declaring: “I did not come into journalism to gag other journalists.”
Speaking at Commons question time, Labour’s Tristram Hunt said the BBC, funded by the £145.50 (€160) annual levy on television viewers, should protect local radio stations rather than pay such high wages enabling staff to employ expensive lawyers to secure such injunctions.
