The state of V Tubers

Why is it always sexual? “I can’t wait to hear sexual joke number 3178, the first 3177 where perfect.” Don’t hate any of these individuals but I encourage them to do more. They have such a large audience yet how many fall into lust with such streams? And then they and others flood YouTube with such clips. Is there not one large social media site where lustful activity is not so common and promoted?
