spam bot repeatedly contacts my website
I have a particular website IP address (buttons-for-website.com) that's hit my website's home page every day for the last several weeks, sometimes multiple times per day. I think its some kind of bot, but I'm not sure. I've tried a Wordpress plug-in to block domains but, as I've come to find out doing online research, these types of hits just bypass any blocking attempt due to multiple IP addresses used, etc. Is there something that can be done about putting an effective block on my domain to block this (and any other) annoying website bot?
