dedBuNNy:WGT is a business, online operating out of the US, but selling their products and services world wide. There are laws to protect consumers in all countries, if you think it's only US and State laws which carry any weight - you're sadly mistaken.
FWIW long arm jurisdiction / law would be unlikely, and that's because it is not needed. The company resides in the US, and no one can seriously dispute the fairness of US jurisdiction / law. You need to get up to the likes of the Lockerbie bombing to find cases heard in different jurisdictions using laws from outside (Dutch jurisdiction / Scottish law that case). Yes one country could break ranks, but common sense tells us highly unlikely for this here, and there would be outrage as to why.
US law is basically English law as used by any English speaking nation (roughly), and other developed nations also have fair laws.
A veritable quagmire of legal hoops exist but those hoops are the same everywhere, same as US. The internet is still in it's infancy as far as people being able to do all this stuff, and laws are not even that far. No doubt WGT are speaking weekly to see how right side they are, and doing only what they need to stay in front. Not defending the state of play but looking around no competitor is up and running offering better and safer either. Bloomin' shame as that level playing field looks very far away to me. I am hoping stern competition comes along as at least then we would have more of a feel for what can be done (I am no IT person), and it may shake a few things up around here generally. Here though is still fundamentally a good platform even if I don't think that platform has been built on as much as it should this year.
If competition ever did happen, and lo WGT start doing more to combat it then they will be needing to build new customers fast. For them to decide on that corporate decision.
