Just don’t invite the whores, I hear they steal lemons…
I feel the need to point out that most of the “problems” you stated about YouTube are due to scale. If any YouTube competitor had to deal with the sheer amount of content YouTube does they would have the exact same problems.
Of course - multiple pre-warnings, which includes contact from social workers with resources to help them find somewhere to go/help moving their belongings. But that would cost the government money, and that won’t fly in the US.
