This platform allows users to generate pornographic content. Including for “underage users.” I hope everyone understands that the notice saying “you can only generate pornographic content if you give your word of honor that you’re 18 or older” is just a flimsy cover‑up. If a user visits a porn site (among other places), it’s only natural that they’ll see vulgar comments there.
As for your complaints — the site is basically being kept afloat by a single person. He’s also busy with work that brings in the money to fund the platform. He simply doesn’t have time to filter comments, he just doesn’t. Be grateful that the guy keeps the whole thing running at all.
Let’s just slap up a big sign that says “Adult site: leave if you’re under 18,” and that’s it. Of course, no one will actually leave, but at least formally, the responsibility will be offloaded.
