While it's certainly better than actively moderating a community...
Is being the admin of a website that actively hosts jailbait and required a massive media outrage to finally remove it that much better? I get free speech and all, but I mean, the subreddit straight up catalogued which pictures were "fap material" and encouraged people (including parents) to take candid photos of the children around them.
A community like that wouldn't last a millisecond in a server I host.
