I just recently started the Spam-O-Meter. The page is pretty crude right now, but I'm working on getting the email address out into the hands of spammers. I plan on having it do graphs of how much it gets each day, and maybe have a nice interface to allow people to access the headers. I want to keep the spam as "legit" as possible (not mailing lists that you sign up for), so I won't post the email addy that it uses. If people know of ways to get on spammer's lists let me know. I'm hoping to get a couple thousand emails each day:)

I've had pretty good success with register.com. Its not the cheapest, but its got a decent interface and doesn't require an initial 2 year contract.
