Yes, it is possible to ban IP addresses, e-mails, and so forth to block some spammers from trying to register. We have already banned
293 IPs and
288 e-mail addresses. Many of the e-mails banned are blocks on entire extensions such as *@cashette.com. This blocks any user trying to register with an address ending in that extension and is much more effective than banning specific e-mail addresses.
We have proof that this method is definitely working to some extent. By checking the ban log, it shows that one banned e-mail address (*@*.ru) has had 553 hits to date!

I think it would be much more helpful if we had some sort of visual verification process included on the registration form.
