Much has been said and written about it, but in the end there is 1 company that is responsible for the software; and that is BETb2b. www.betb2b.com
In fact, there should be a list of all the sites they manage to notify users. It may be that there are also a few good sites in between, but that chance seems very small to me.
And if as a company you are going to do business with betb2b, you also have to bear the consequences if you know that many of their customers are cheating. I will see if I can make a total list.
It is easy to compare, as all sites have the exact same layout except for a few colors and letters.
