Baron, you're right. Although ISP's cycle IP addresses once in a while (6 months or more can pass between changes).
How about requiring a regular e-mail address, instead of free web based ones (Hotmail, Yahoo, etc.) for an account. That would mean that someone can't create aliases using the same e-mail address or use several (free and fast to set up) e-mail addresses to mask. Is that feasible?
