It may appear to be less hassle short term but trust me they are losing their business long term if they are this unprincipled.
They are not losing all of it I would say. Basically if a gambler is fond enough with a site, it will not be much hassle for him to access it through a proxy. However as a unlicensed gambling site, the risk are far greater than keep on serving business for the UK customer .
It will be much of a nightmare for you because you might see the legal feds knocking on your front the next morning and this would be the reason that most unlicensed sites has taken the safety precautions rather than facing the law in the future
It seems FortuneJack has follow the other fellow gambling sites as well
We have added Great Britain into our list of blocked regions because online gambling is illegal there. In the past we had blocked several US states for the same reason. Although, we are working with gambling commission to resolve the issue as soon as possible and meet the country regulations.
