Is there a site listing which casinos are owned by the same company?

[WhoIam]

I've been doing quite a bit of casino whoring in the past month and have frequently run into the following two problems: 1) I sign up for a casino, deposit, and am then informed I'm not eligible for a bonus because of an account for a sister site; or 2) I sign up for a site and am immediately banned.

These sites often state that having an account with a partner site isn't allowed, but they never mention what those sites are. I'm sure I could find this out by doing a bunch of research, but this isn't worth it when compared to the minor hassle of not being able to receive a bonus from a site.

Is there a comprehensive index of which groups own which casinos anywhere? I know some sites like casinobonuspages mention this for a few, but it would be helpful for this information to be all in one place.

Have a look at Arnold Snyder's site, http://www.blackjackforumonline.com/BestInternetCasinos.htm
There is a wealth of info there for the bonus whore.

The easiest way I have found is to click on the affiliate/webmaster link at each casino before you sign up and they usually show all the sites on one page so you can tell if you have hit one of their sister sites.
