LiveJournal, a combination of blog (web log) and web forum, has recently gotten spammers, who leave comments saying "Take a look at this link". The LiveJournal admins have anticipated this, and just recently put into play some anti-spam techniques:
* Anonymous posters are only allowed a small number of posts per time unit per IP address before they have to prove that they're human through captchas (see http://www.captcha.net/). Registered accounts are allowed a higher rate of posting before they have to prove their human. * When journal owners delete a comment from their journal, they now have the option to mark the comment as spam. Comments so marked can be reviewed by humans, who will delete the posting account if it really was spam. * If someone posts a burst of comments to many different journals, as opposed to the same journal (where a burst of comments would just be someone participating in a discussion), this will be brought to the attention of humans, who can determine if it's spam, and delete the responsible accounts of it is spam.
