I still don't see what you mean about Hotmail -- I create a Hotmail account. I give it all bogus information, including bogus personal information. I have QuickTopic send a verification notice to that account, capture the URL and use it to generate my QT account. I promptly forget about that Hotmail account. This generates more spam to my real email address how?

It's kinda funny to talk about limiting spam, anyway. I've long abandoned that fight. I get 400+ pieces spam/day on a mail account I've had for years. I just filter/delete it. I don't even know how I'd indentify it if I got more spam as a result of signing up for some service or another.
