Some of these (IP throttling, limit per email address) help multiple registrations on a single server, but not farming registrations across the network (not that this makes them bad things). > Wards off 99% of Spam Registrations on lightwitch.org alone. Ah, this is good - I don't think anyone else is collecting statistics on how this stuff works (if they are, please share). Do you have a breakdown of how the different preventions contribute to the 99%, and how do you detect the remaining 1% (and gain confidence that there are none not detected)? /K
