In recent days, spammers seem to becoming smarter and smarter. Adam Kalsey points out a new technique whereby spammers post comment spam that links to other blog entries. But on inspecting those entries one sees that it has been flooded with spam. The problem is, many weblog authors don't really care about spam and won't remove them.
In fact blog spam has reached such heights that The Register has written an article on the subject and mention MT-Blacklist. If you are a weblog author that is bothered by comment spam, you must install MT-Blacklist
Another new technique comment spammers have discovered is using HTML entities in their urls. For example rather than
something.com they enter in
something%2Ecom. In the browser's eyes, it amounts to the same thing and Blacklist wouldn't catch these spam until recently when Jay released v1.6.5
There are other ways as well to combat comment spam, Elise has an entry guiding you through various ways in which you can protect yourself. Neil's got a tour of MT Blacklist 2.0 rc6 that was released to us - the beta team - yesterday !
