You'll look at anime or animations on youtube once, you'll start getting vids and channels recommended with nsfw content that are not even age restricted

Then pornfags get uppity when anyone says that they're targeting kids because why would you upload content that is meant for an adult audience, on a platform where minors are the majority, without actually age restricting your content? It's obviously because you want them to find it.
Any counterargument against this wouldn't stand a chance in a court of law.
