Couldn’t we theoretically screw with this up, given that Reddit has porn subs, and force it to be rated Adult? I bet that this would leave plenty advertisers pissed.

Nah, they’d just do the same thing for Android that they already do on the Apple store.

Basically the app you download is locked into a SFW-only mode and then you have to log in to reddit via a web browser and flip a setting that then allows your app to show NSFW content.
