Get rid of comment spam part 2
We installed MT-blacklist before in attempts to reduce comment spam, but this is more a passive approach to the growing list of comment spammers on the web.
Google in conjunction with other major blog players on the web have come up with a new standard to make comment spam unprofitable.
Basically, people leave comment spam to a URL for something like pharmaceuticals on hundreds of little blogs. This is easily done because most comments are inserted the same way into blogs and it provides spammers an easy way to publish links to their sites on hundreds of websites at a time. To make this effort useless, Google has suggested all bloggers start using a new tag on all URL'S submitted to comments that will make it so that the link will not boost a URL's search score.
If you're using a public blogging service like blogger or blogspot, you should be already covered. If you're running a service like movabletype you'll have to find a way to modify your install. Fortunately for movabletype users this is easy enough.
Your comments will change in the code of the document but should work the same as before. As an Example:
That comment would be transformed to
Links created outside of the comment section will be left alone.
Hopefully this will be a proactive solution to get rid of comment spam soon.
