"For services hosted in other countries the law in those countries might well have something it can say/do"

The actual hosting country does not always matter. In the Netherlands for instance (i can't speak for other countries) -where- a service is hosted is irrelevant. If you market your service to Dutch citizens (you have a Dutch language version of the site, or a Dutch contact number for instance) you are assumed to abide by Dutch law and can be prosecuted in a Dutch court if you don't.
