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).

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)?
