I have just installed this plugin for VB4.2, thanks!

I tested it by creating new users and it worked as expected, placed the user in the newbies usergroup and moderated their posts. However it isn't moderating the spammers, their accounts are going straight through to the registered usergroup. How is this so? If I try again and make an account, it always works correctly for me but not the spammers

What could be causing this?

The plugin is doing something, because it says its blocking user registrations in the statistics area.

Thanks again.
