Spam…One annoyance to running your own blog. I recently enabled Akismet to cut back on the amount of spam I receive. I was getting on average about 5-10 bogus comments to approve each week. Most of them had major typographical errors or were intelligible.
“How does it work?
Each time a new comment, trackback, or pingback is added to your site it’s submitted to the Akismet web service which runs hundreds of tests on the comment and returns a thumbs up or thumbs down. As a result, you don’t have to waste your time sorting through and deleting spammy comments from your blog.”
A lot of these spammers are using blackhat SEO techniques in order to improve their rankings on the search engines. Sounds to me like a lot of it is automated and very little human interaction is involved. I do wonder what the return of investment is in writing a script that just spams blogs.
