I called my host about this and they said to put that in place would do the job but it would severely slow down the performance of the site so I opted not to. Right now if someone tries to log in with an invalid user name they get blocked for a couple of hours. That will do the job for now but I get an email every time that happens from Wordfence (my option) so I can tell and the emails are just rolling in. It gives me anxiety. I'd rather just block the whole country since I'll never do business with any of them.
