Re: How to control spam registration?
There’s a fairly simple and foolproof method to automate spammer deletion. It’s easier to let them in and then delete them automatically than to try to stop them from registering in the first place. Otherwise it becomes an ‘arms race’ type of thing, as well as a game of keep-up-with-BP/WPMU-changes if you try to integrate it.
See it in action at http://visarus.co.uk/bp-spambusher.php – every time you visit that page you will be cleaning up spam registrations for me 
I can put it on CRON if I want but I enjoy the satisfaction of seeing how many registrations I’ve deleted 
40 in the last 24 hours.
