That's fine. But they NEED to ban people using their service from spam else they would dominate. That is what people don't understand.

It depends on the country and the region, but I have faced issues multiple times with not able to make any progress with the government. It happened in much more important cases like passport, for which if something fails on their system, you are screwed.

Nobody provides support in government services as well unless it is required by law, and I have been locked out of government services. In countries like China, you could be locked out of government service if your credit score is low. In Sweden you could be locked out of it if you don't allow unions.
