I was doing a search on Google and I got pretty deep in the results when I stumbled across a web site that is selling access to user names and passwords to pay sites.

I won't post the site here so that it does not get abused, but they claim to add tens of thousands of sites daily. I tested some of the samples and I was sent directly to the members section of that pay site.

For more details or information, private message or ICQ me. You may already be aware of the site as it looks like it's been around a while.

I'm not sure what you can do legally if you find accounts for your site, but you can at least disable the account and stop access.
