The following notice has appeared on Wikipedia today when many UK users attempt to edit content:
« Wikipedia has been added to a Internet Watch Foundation UK website blacklist, and your Internet service provider has decided to block part of your access. Unfortunately, this also makes it impossible for us to differentiate between different users, and block those abusing the site without blocking other innocent people as well. »
