True, somehow I mixed them both

Not an expert by any mean. But if they already did it with canceling the insurances of the Russian planes, banning effectively from the common European airspace, I see high chances of successfully implementing this.

Every country is sovereign in its territorial. This means that they can:

• confiscate actives in japan
• to pass fines
• to ban the access to the servers
• to ban the operations on its territory
• to jail the company’s representative of the country
• etc etc

As an example the EU did exactly this when the gdpr came into play

Most of those moderation just step in the moment the lie enters the chat.

And no, you freedom of speech does not allow you to lie without facing the consecuences
