If Reddit has a problem, it's not the low quality content, which I'm totally fine with, depending on my mood. The problem it has is that it was targetted as a recruiting ground by hate groups. The red pill/gamer-gate types and stormfront guys are toxic.

Also, for the first few years of its growth, the most popular search term that lead people to the site was 'jailbait'. That's the kind of community they nurtured and catered to.
