Semi related for all the programmers, and makers of online services, and similar providers, doing stuff on their own: nobody is going to care about your obeying regulations , compliance and rules about your thing until it gets big enough.

Obviously avoid some things! But that list is very small. And for that there is the dark web which has its own rules.

But all the other stuff ( usually legit ordinary stuff) can be safely ignored until that site or service is more than a one person show , or never, whichever comes first.

Usually people who have good ideas do not have much money, and many are intimidated by this or that law or regulation which the rich and well connected use to prevent more competition .

If one gets to that point the regulations are starting to have teeth, then that is a sign of success. And most probably profits, which can be used to fix up the service to comply. Or shut down and do the next idea
