If you aren’t using Automattic Kismet (Akismet for short) on your blog, it’s time to get on it! Everyday Akismet blocks about 100 spam postings by linkers.
Why so many?
Spammers are trying to get links to their website by posting comments on Blogs to increase their link popularity. Whether the search engines actually pay attention and count the links from blogs is highly questionable. Almost certainly Google excludes these links, but MSN may count them and Yahoo probably counts a few of them.
Why do they keep doing it if they all get blocked?
Obviously nobody is checking or they would see right away their comments aren’t being posted. If they aren’t checking that probably means they aren’t doing it themselves and they can’t be paying whoever they have making the posts very much.
Looks like freelancers in China, Russia or India.
