Seems to work alright for me with 4.1.1, except that timezone 3 seems to still get through and I am not sure how to do timezone 0 or GMT.

Try the newly uploaded version 1.2. :)

It works for me on 4.1.5

I know for certain that I went from approx 15 registrations from russian i.p.'s almost every day down to zero!!

I mean really, why would a man need all that viagra?

I have been getting hammered everyday with multiple registrations. I have most timezones banned except USA ones. However, I cannot seem to ban GMT. I tried 0, tried +0, nothing seems to work. What am I doing wrong?

This is an awesome MOD that worked great for me with 3.8.x, but does it work on 4.1.11?

If not, can we make it so? I'm now getting spammers no matter what and this really did the trick for me as I only want North American, Canada, Mexico, USA, Puerto Rico, etc. time zones.

Nice mod!

works on 4.2.5

only problem is that it won't take time zones like +5:30. That and the default message tells them indirectly to just choose another time zone.
