People who want privacy use Tutanota & Protonmail, not hackers. Maybe some hackers use those services, but the majority I imagine are doing it to stop their inbox being read by arbitrary surveillants.
Also many hackers are cypherpunks and love anything encrypted, so I can see the correlation to be made there, but again, those people are like 0.001% of the encrypted inbox users.
Splitting the effect in false/true positive/negative results for their anti-hacker defenses is more meaningful, especially as there are way less hackers than legitimate users.
So what's the abuse here, people creating new Tutanota accounts to get access to more "free trials"?
Crunchyroll seems to be aiming for the wrong target here, they should clamp down on the free trial by asking for a payment method that doesn't get charged until you run out of your free trial, and can't reuse that payment method on a new account.
If you really care about abusing the free trial you can spin up a new account on a new email, along with a virtual credit card with a service like Privacy.com then cancel the card before the transaction can be made.

I don’t understand why that’s understandable. What difference does it make and how does it keeps things “tidy”?
