After deleting WordPress spam for another hour or so, it became clear to me. Enough is enough. Either I would register a bunch of Akismet keys (Enterprise or Pro) for some of our websites or develop my own SPAM protection plugin. I took a closer look at the hooks available for comments and accepted the challenge. A few hours later my first prototype was ready. It appeared to work as I did not receive any comment SPAM for 2 days but this could be a case of serendipity. So I updated the plugin with a counter indicating the number of SPAM comments stopped. As for now the plugin stopped over 100 spam comments and I didn’t have to delete a single comment. As of yesterday the plugin became available in the WordPress Plugin Directory. Feel free to try it on your website and keep me posted.
