Web Site Spam Bots
One of the biggest problems facing webmasters these days is the use of spam bots. A well known SEO Expert Jim Westergren talks about comment spam on his blog and what he has done to battle these issues.
Spam Bots are generally used to seek out blogs, forums and even guestbooks that are exploitable to comment spam attacks. For example, let’s say that a certain version of wordpress had a security issue where the captcha verification could be bypassed (a method used to help prevent comment spam because a user could have to enter in the security code from the image). The spam bot would go out and find blogs of this version and then insert spam comments into the comments section of the blog post.
One of the keys to preventing spam on your sites is to make sure you are running the latest version of your blog, forum and guestbook software. Try to keep away from companies who are unknown as they are usually the easiest to attack because they come out with a version of the software and then often fade away when expoits come out for it.
