Credit card ban solves nothing about problematic gambling. People who need credit are dead in the water anyways.
Well, nobody will agree with the above but I guess it is not a rocket science to top up a prepaid card by credit card (maybe it is I never had a credit card if I recall). So the effective ban will be much more complex thing. Probably doable after some time. Still people can take cash from credit cards (with hefty fees) right?
But UK market is dead. It is the worst affiliate market on planet for new acquisitions. It can not get worse. So if there will be some stupid restrictions and if the black market flourishes, it would be great.
I still have doubts. Australia is not great market either now. The developed countries have much more effective censorship than developing countries. Developing countries use some hard bans which can be avoided. The developed countries use hard bans still less, but they effectively combine them with soft measures, which in the first place are voluntary steps by gambling operators and then the regulations of the economy as a whole (like bank restrictions, which is effective in countries without alternative payment systems like hawala).
What really scares me is that nobody thinks about implications what can happen if employees of gambling companies have to check whether someone can afford to gamble. It is obvious those data will be de facto public.
