So I thought about it a little bit.
I had this idea that the app was 13+ because that was what was (sort of) logical seeing the restrictions. But ok, it is actually 17+.
So, if I understand well, one has to be 13 to have an account on the website, but is not supposed to read the mature series/ pages before they are older (17?). Ok I understand that.
So at 13 one can read the not mature pages, including all the very questionable content but with no applicable warnings. That's ok, because it's not Tapas' job to police that. But then why warning non sexual nudity? It's senseless (or even very, very questionable in certain cases for eg. nudity in other cultures. The idea of doing that is sending shivers through my spine. And it seems to go against the other messages of Tapas. I do understand Tapas has no influence on a censorship issue like that, but it's shocking nonetheless).
But then the next, more Tapas-related issue. So if I understood well (tell me if I'm wrong), tapas website is both 13+ and 17+ or something similar (if mature warning). But the app has more restrictions than the website. So it cannot be 17+. It must be 15ish+
There is a 17+ website and a 17+ app which are different enough to absolutely need more explanations.
It can't be just 'the app is 17+' and that's all.
Unless I missed something!?
