proben on "[Plugin: Wordfence Security] Auto block by URL"

Hello,

I have the same problem.
I'm trying to block all bots that use "action=register" request and also "/register/". So I added following URLs:
/wp-login.php?action=register, http://mysite.net/wp-login.php?action=register,/register/

but still I see that bots coming to those URLs and their IPs are not appearing in the IP blocking list.

Thanks
