How do I prevent SpamBot activity on my website?

Secure your web forms and comments

Disable/Secure Logins

To prevent SpamBot’s from repeatedly filling in Fake Users, you can secure the login with a plugin if you use a CMS (Like WordPress) or you can limit the login attempts.

Update your software

SpamBot’s are an increasing bane of web master existence and so many CMS developers are including more SpamBot preventions within their software. If you are sing a CMS, you will want to make sure your version is the most up to date.

Email account Visibility

Hide your email address. Many SpamBot’s find your email address in your website because the email address is in plain text for all to see. Use an image to display your email address if you need the email address on your site. Otherwise, do not have a plain text of your email address on your website.

Review your logs

It is a good idea to review your logs of those who accessed your site. Most CMS programs have a plugin for this. For example, WordPress has the MVIS Security Center plugin that monitors this. You can view your logs and those who accessed your site through Shell (VPS or Dedicated servers only) or cPanel AwStats as well.
