If you come across adult content and it’s properly labeled as such, (I.e. profile and posts are labeled as no minors), it’s your responsibility to block and curate your own feed. If you’re unable to do that on your own, you should have someone monitoring your internet access.
Getting really tired of the rhetoric of “there’s minors on this app!” when someone comes across adult labeled content. There’s minors on every app; it doesn’t matter who it’s marketed to, and anyone with a finger and internet access can press download without consequences.
