I’m now using two plugins to help me combat comment SPAM. The first is Kitten’s Spam Words, which gives you an easy way to delete comments and mark them as spam at the same time. This helps to create a list of comment spam words in WordPress so that further comments will automatically be held for moderation. The second plugin is Mark Ghosh‘s Three Strikes Spam Protection. This plugin will automatically delete a comment if it matches a certain number of criteria (default is 3 strikes) so that I don’t even have to moderate them. It’s configurable so that you can set the number of “strikes” to delete a comment with.
