When I create a new e-mail address, it’s clear where the spam originates, especially if I use that address officially. You can always see who sells it or “accidentally” lets it leak out.

On the other hand, if you create a Gmail address and NEVER use it, it gets SPAM eventually, but not necessarily within the first 30 days. No telling how that happens….

So, it’s a good experiment but not one that will probably produce meaningful results unless the users use the address in newsgroups, sign up for Blue Mountain Greeting Cards, etc.
