It’s been outlined here for a quite a while:

Generally we reject about 30% of the programs that apply. We do this if we think there is enough reason to believe they are or will be a problem, examples include the late Warren Cloud Casinos, Casino On Air, Casino On Bar, Be the dealer (Be the Stealer), 1CNP, Cashwave and a long list of others over the years.
Have we de-certified programs? Yes, actually more then I care to remember. Of those two very large ones made the changes to their program we required and they were admitted back in. Most were never allowed back.
We just recently had a situation where we pulled certification on a program until they got rid of a retroactive clause in their terms and conditions that members found offensive. So we take certification very seriously and this is why I bristled when you made those comments.
Hope this helps clarify the question a bit.
