UK computer users are battling to contribute to the online encyclopedia Wikipedia – because the site has managed to get itself blacklisted as child pornography.

The UK-based Internet Watch Foundation blacklisted the site when it ran and article about the heavy metal band, Scorpions. The article was accompanied by a screenshot of the album cover, featuring a naked young girl.
Although the girl's genitals are obscured by a simulated tear in the picture, it was enough to get the site on to the blacklist.
Almost immediately, the main UK ISPs shut down access to the article – and stopped users from being able to contributed to the Wikipedia in the process.
Wikipedia refuses to remove the image.
