WordPress Anti Spam

There are several WordPress anti spam plugins available, some free, some free only for non commercial use and some you hav eto subscribe to.

The free version of this plugin focuses on WordPress spam comments. WordPress spam comments are often generated in thousands by bots, and are a total waste of your time. This plugin prevents WordPress comment spam from bots.

Anti Spam Free Features

  • prevents automated comment spam
  • stores the comment for review in the spam tab
  • remove the spam comments from WordPress after a defined number of days
  • option not to remove comment spam automatically if desired
  • whilst another spam plugin should not be required, as in our opinion this is the best anti spam plugin for comments created by bots, this can run alongside other spam and security plugins

( the remove function will work on previously spammed comments, so can also be used to clearly down historic comment spam if that has built up from another plugin )
