In a follow up to a previous article, it appears that comment spam is becoming a very big problem for blogs. As a blog administrator you want to get feedback from clients and your readership, but you just keep getting messages from spammers who just want to siphon off the page rank created by your diligent article writing. You could turn off the comments, but that would negate one of the benefits of blogging. You need a filter, and after exhaustive research I have determined that the best one out there is an excellent creation from the folks at Wordpress. It is called Askismet, and is available as a plug in. Check it out.
