The EU has different norms. Bafflingly to me, it feels like the EU had an existing expectation of linking everything you do to your full name and address and then trusting the police to stop you getting swatted. I don't understand this attitude myself but you can see it in impressum laws for example, business registrations, needing your personal info to give feedback to parliaments, it's clearly a pervasive social norm over there. I suppose the reason they don't get swatting is that the police will verify the ID of the person who calls in the report.

Imagine believing the police shouldn't murder you based on an anonymous report.
