You can't create a Google account these days without a phone number, and you can't reuse phone numbers. Worse, in my country, you need to register to get a phone number (anonymous /unregistered sims were outlawed a few years ago).

Interesting. Must be a geographic restriction.

You don't need a phone number. But it is not obvious how you can get an account without one.

You can get digital disposable phone numbers online

Google/Facebook block those.

This is understandable, though it then creates a new challenge: problems that have always existed with hearsay and rumour are greatly exaggerated by the speed and reach of modern technology, and now we have reviews that come from unverifiable sources, which can cause real damage to a person or business, who in turn may have no way to defend themselves even if the review is malicious or inaccurate.
