>The outcome? It became a haven for child abuse content
This is the ugly side of not being able to take down or moderate content. Many years ago I ran a small file-hosting page that started as something for myself and friends. You would not believe just how quickly people/bots began to upload illegal content of that sort. Ultimately, I got tired of dealing with that crap and just shut down the page.
I'm mostly okay with the current balance of freedom/"censorship" on the net; people can still host their content, no matter how anti-mainstream, if they are really determined while outright harmful content is more or less sensibly dealt with.
