Well, casinos who's employees shill or spam forums for a start...

Basically casinos are blacklisted, or rogued, if they do not play fair with their customers.
Some of the main factors are;
T&C's must be clear & concise & the casino must stick to them.
Casino's should not invoke some vague 'bonus abuse' clause to withhold winnings.
Customer Service queries should be answered within a few hours max and be concise, accurate & professional.
Players withdrawals should be paid as quickly as possible (7-days absolute max).
The software must be fair & truly random.
