If you own one of the user accounts that were locked down and you think that was a mistake, please let us know. You will have quite a lot of explaining to do, though.

Note that this incident was not a security breach of the site — registered users uploaded attachments to their own homepage, which is a perfectly valid thing to do. However, the attachments were full of links to sleazy sites, whose purpose was to increase the Google rank of those sites.

Sorry for not noticing this immediately. Hopefully, this incident didn't cause too much damage to the site's reputation, and the BlackListPlugin as well as better awareness of the problem will hopefully prevent this from happening again.
