Do you have Stop Forum Spam installed? It won't stop all registrations of spammers, but it should get a chunk (basically anyone who's been reported to the database as a spammer will show as a spammer, but like a captcha it won't always stop a human capable of updating their connection settings through a proxy).
As for the phishing page, you'll have to report them to their ISP, domain registrar, etc. The service looks like it's run by:
