Presumably advocates of NSFW content on large social networks don’t see a problem with it. Hopefully you see where the other user was coming from now; not looking for you to agree with them.
I do but I think their point wasn’t well made, and is frankly misleading and wrong.
There are very specific kinds of content that lead to these kinds of bans. Pornography and organizing violence are amongst them.
It isn’t about controversial content.
But that's not really true, for example reddit has a massive amount of porn and yet none of the reddit apps get banned.
