You can get away with quite a bit just by being silent, and for longer than you'd think. A big way that people get away with things for so long is just by not answering questions. Someone says, "Is this [illegal thing] yours" and you say nothing. Now you've got to burn hours and dollars trying to prove someone owns something so that you can go after them.
You'll find domains, web hosts, countries, and employees who are all onboard with the same philosophy. When everything requires a subpoena at the highest level to move something forward, it can easily take years for anything to happen at all. Some countries are known for having slow legal systems. Stack jurisdictions with slow court systems and you can start with an 18 month window before anything can happen.
You've got a domain in Tonga registered to a company in another country, owned by a large company in another country owned by a trust in a third country. Often small countries with limited resources and archaic or corrupt bureaucracies. And where is it hosted? That's probably another connect the dots. And the site can change hands and then you have to start all over again. Are you going to refocus on the new owner or are you going to spend even more resources trying to track down the former owner?
And any of these entities may lead to nothing more than a mule, fake person, or dead person. Sure, it's someone's fault for having inaccurate records—but who? How long has this been going on? Did they know? Was it intentional? It shouldn't be like this, but it is… what do you do now? Are you going to go after the recordkeeper too?
You can do illegal shit for years or even decades if you just say nothing and respond to no one.
