Starnet/World Gaming has been subject to a good deal of investigation by the Canadian authorities due to their marriage of online gambling and pornography marketing. In addition it has long been alleged that they were connected with the US based Hells Angels and other organized crime groups.
Their reputation with licensees and affiliate webmasters has been horrid.
While most private label software providers dont have quite as colorful a past as Startnet/World Gaming there are quite a few that have bad reps for financial performance and I recommend you perform an extra level of Due Dilligence before choosing one to invest time and money with.
“Caveat Emptor” is the prime directive here. (Let the buyer beware)
