First, thank you for posting this and trying to help. I installed this along with other suggestions from OZZY.

Renaming "register.php" is now fairly useless against the latest spam software. It was a good idea and probably once worked quite well,, but spam software (xrumer, etc) must now just be looking at the register link to figure out the URL, so the filename really doesn't matter anymore. I renamed register to completely random numbers/letters, two separate times, and all settings are correct. Within 30 minutes, the spambots are filling out forms on the new register filename. I know they are getting past the rename plugin trick because I'm getting PMs with them being blocked by a separate hostname spam plugin (which does help eliminate some spam).

I wonder if implementing a javascript generated version of the link to register.php (or whatever we rename it to) would block them again for a while, until they figure a way around that as well. That is what some websites use to reduce email harvesters.
