So far I just ran about 10 keywords that would take out ~95% of all the Spam that ends up on a wordpress blog, I seem to get an endless repeat of certain fashion brands and a the occasional search engine optimizer. The remainder I looked so every now end then if I add a post or do an update. Before implementing OTP (One time password) there was a simple captcha on the site which presented a simple math problem for you to solve and I’ve been using reCaptcha from Google for a long time on the homepage to obscure e-mail addresses so they do not get harvested for e-mail spam etc, there is a post about it from a couple of years ago. So, I went to have a look if there is a plugin available that uses reCaptcha on WordPress and found more than one. You have to register with Google to get a unique key for your domain and then enter that in the plugin and you are good to go. Unlike the previous captcha this one so far stopped more spam thus far and you can see it when you want to leave a comment or have a look at the ‘Contact Us’ page. You probably will need to keep a few keywords to deal with the few that still get in.
