They must oblige within a certain time frame — even if your account has been suspended and I believe even if you’ve deleted your account. Curiously, this might be one effective way to protest. Golly I wonder what would happen if many people requested such reports simultaneously. It seems these must be processed manually by admins.
As a bonus, it’s nice because all your comments and messages are searchable.
They are legally obligated for some US citizens. California (~40 million people) has a law similar to GDPR.
They also don’t have a way to check where you live so you can do the request and select either option (GDPR or CCPA) and they will fulfill the request.
