It really is unfortunate that many of these affiliates, go by the wayside, yes it would be nice to be able to have a blacklist option, Yes it easy to change affiliate links but as many know, sometimes simple changes can affect site rankings, so besides getting screwed by the affiliate, sometimes its more than that, its site rankings also.
I just recently had to change many links on a site not casino related and after my site was ranking well it is now buried down a few pages.
