I hear this defense a lot, but isn't it kind of problematic that a platform makes you go out of your way to tell them you prefer not to see soft-core porn? I didn't even know TikTok had a "Not Interested" button until someone told me in person. It's completely hidden.
I've personally seen this come up on a lot of different social media apps that feature video content. They all initially throw a bunch of vaguely pornographic content at you to start with and continue doing so unless you keep opting out for long enough. I kinda wonder how many users never make it past the initial onslaught and just assume the entire platform is like that.
Meh you're just telling on yourself, here. Mark them as not-interested. My feed is all scale models and noodle recipes.
