Disclaimer: IANAL

If I run a service, I can add pretty much any requirements (barring anti-discrimination, accessibility laws, depending on your jurisdiction) I want for use of that service.

If I saw you can't use my service unless you do so while wearing a chicken hat and humming God Save the Queen, I have every right to do so and every right to kick you off if I discover you were wearing a turkey hat instead, because it's MY service. I may have a hard time enforcing such requirements, but nobody has a LEGALLY ENFORCEABLE RIGHT to use my service without my permission, no matter how dumb my requirements are to be granted that permission.

Note: The above obviously doesn't automatically apply to existing legally binding contracts such as with a paying customer, though in most cases either party is free to break the contact at any time assuming they are willing to pay the penalty specified in said contract.

Right, but their policy is that individual users can still get keys for personal use. So given that, how could individual users getting keys for personal use be a violation of their policy?
