If you own a blog, then you are probably familiar with spammers. Spammers try to leave comments on millions of websites in hopes of promoting their services. They hope that the webmaster will ignore such a spam and that it will not get deleted. They might also hope that other visitors to the site will see this spam and read it. If you do not want your loyal visitors to be exposed to too much spam, then you need to take some measures. If you have a WordPress blog, then setting up Akismet can be very useful. There are also other plug-ins that can help spam, but it is also important that the webmaster himself will not tolerate any spam on his blog.
