Block Spam on WordPress, Multisite and BuddyPress Using Math Questions

If your WordPress site doesn’t have protection from spam, then I guarantee you that you’re spending too much time sifting through spam comments and deleting spam registration accounts from your site. Spam is a common problem for WordPress sites, because bots have been trained to find vulnerable sites running on WordPress.

Block by Math Reloaded is a new plugin that was based on the Block-Spam-By-Math plugin created by Alexander Grau. It adds a simple math question to spam-vulnerable areas on your site. This new plugin is primed to work with WordPress 3.0. Check out a screenshot:

As you can see, it has a simple, unobtrusive implementation. You can edit the two rand functions in the plugin file to generate whatever type of numbers you want. Check out the plugin’s homepage for more screenshots.

Block by Math Reloaded works on:

  • WordPress single-user
  • WordPress Multisite
  • BuddyPress 1.2.7+

Block by Math Reloaded protects your site in the following ways:

  • Registration forms
  • WordPress login
  • Comment forms

BuddyPress Spam Protection
One of the best things about this plugin is that you won’t have to install separate plugins for your registration form and comments. Fewer plugins is always a good thing. Install Block by Math Reloaded and you’ll get intelligent spam prevention for all areas of your site in one package.

Block by Math Reloaded is a proven tool for reducing spam content on WordPress sites. If you don’t currently use spam protection, give this a try. If you’ve already been using the old Block By Math plugin, you may want to look into this one. Simple math questions are much more enjoyable for your users than funky, illegible CAPTCHAs. So give yourself a break from spam and implement this user-friendly solution today.
