I dont think minors understand how dangerous it is to be sexual on the internet. To have a nsfw blog as a kid, even if you dont post original content, can put you at serious risk.
There are predatory adults who can pretend to be your age, or attempt to get close to you through the kink community.
I cannot stress how unsafe it is to be active in nsfw communities or reblog nsfw content as a minor. This is why I do NOT support minors in kink. It’s because I don’t trust predatory adults to keep their distance. It just isn’t safe.
