Hello,
It's a theoretical question, but I'd be interested in your opinions. There is a website which allows people to have one-to-one conversations with each other, without having to register. It's like Omegle (which has plenty of apps on the Store), but it's not an English site, and users have to provide their gender in order to chat.
Anyway, If I decided to make an app for it, I'm afraid it would be rejected on grounds that it doesn't provide functionality to block/report certain users. However, the site itself has no such functionality, and to be honest, neither do Omegle apps on the Store -- and they got approved somehow.
Do you see any chance for an app like this to get approved?
