It's driving up the cost and expenses. Operators of legitimate sites don't have to worry during that probation time about anything with the exception of customers in Spain during LL match hours.
LL has ~10 matches / weekend (Fri/Sat/Sun/Mon), that means pirates have to have about 40 domains/CF integrations per month plus more in standby - and more, for longer probation periods.

I dunno... stuff like basic KYC measures would be a good start. Copies of ID cards. Government business licenses. Private entities (credit bureaus). Even phone number verification is a serious hurdle for malicious actors, and it ties activities to real world identities that can be held accountable.
Dangerous stuff (e.g. streaming) could only be made available upon a security deposit.

No, and that we let ISPs get away with ignoring abuse@ emails is part of why the Internet is such a nasty place these days. You need a license to drive a car on public roads, you need an expensive license to fly a small plane, and you need a goddamn massively expensive license to fly a widebody aircraft. So why shouldn't you need to pass some set of verification before you get access to inarguably the Internet's most powerful data pipes?
