Ah yeah you are right. I had thought it was UK they had closed down their services to. As for why let them slip through might be because its only a dice site. Weren't all the other sites which received the email from the UK commision , more or less a casino or a sportsbook ?
They might not be targtting dice sites probably because it is not a competitor to any of the gambling sites as dice isn't a standard gambling game offered in fiat based sites.
