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.
Just because it’s not immediate doesn’t mean it’s not automated. As a developer I can assure you nothing about these requests are hard or hurting Reddit in any way. At my work I’ve done these types of requests and the very first thing we did when the laws passed was wrote a stored procedure in the database to do it. Took a few minutes. We haven’t automated using it because we don’t get many requests, but doing so works again only take a few mins, an hour max by 1 dev.
