Hi again!
Another challenge I have is on one site, users keep signing up multiple times with more than one account. That's a problem, as multiple accounts is against our site's TOS since we frequently have votes that are one-vote-per-account. Our legacy system that we killed when we moved to Drupal had built-in IP logging every time a user logged in, so we could go in and check IP addresses in case we suspected a duplicate user. We could also see the IP address someone signed up from, and match that against any recently logged IPs.
Aren't most of those things logged by the stat module already? If you don't need to prevent creation of new account upfront it'd be easy to build up a query to get a list of suspects from what's already logged.
