I simply block traffic from countries where I do not do business in. I used to see constant attempts to mess with Wordpress URLs, which I know is not legitimate because I don't run Wordpress. Cutting out Russia & China basically removed this problem. I really hate locking up my tiny corner of the internet but I don't see another way.
