The damage though has already been done, as previously stated. Hundreds of sites either reproduced or slightly altered the Sun's story without so much as even doing a cursory check of the facts, which would have only involved visiting the Ummah.com site and looking for the thread in question, which was hardly difficult to find. Those stories will remain up, even when the original has disappeared down the memory hole.
Update: Jon Swaine, who wrote the Telegraph's follow-up report on the Sun's story, emails in:
I thought it might be helpful to point out that my take on the Sun's story for telegraph.co.uk is top of the Google News list linked to in your latest post on this subject.
And while your main point - that barely anyone bothered to check the details before ripping off the Sun - clearly stands, in fact I did wait until contacting Sajid at the forum and my story does make clear that it was a call to start a 'polite letter-writing campaign', rather than anything more sinister.
Given that my story is top of the list you link to, and may be read first by your readers, I thought there might be a better way of illustrating your point - eg linking directly to the Mail, PA, Guardian etc versions of the story, which indeed faithlessly reproduce the Sun interpretation.
More than happy to oblige.
