I know you been irritated on what you’ll be receiving every now and then which comment(s) who point you in any pharmacies and adult sites that actually a SPAM comments did by others who trying to optimize such sites? or they just want to let you know about their freakin sites? i don’t have idea at all..lol so of course you want to get rid on that right? ok let me help you a bit, me personally if ill be receiving a lot of those comments first thing that i will do was to activate my askimet plugin no worries is already on your plugin page just activate it and put the askimet API key on it to automatically block such kind of comments and if you asking me where do we can get that API KEY? just simply head over into the wordpress.com site it self then sign up for free blog and as you created your blog, into your account you’ll see the API Key Code that you can use to activate your askimet on your self hosting site using wordpress..quite difficult? but sorry we don’t have a choice to do it and get the free API key because only wordpress.com can be the one who can give us a free key on the plugin..
After all that, you’ll guarantee that your blog is safe in such spam links and please do your comment in moderation so you can check out those commenter links and comments before the approval so you will see either if they intend to spam on you or not..thanks
