Sure. There is no way to eliminate whacko conspiracy theorists and fringe forums. They existed before social media too. The idea is that interpersonal dynamics can help manage these things: if your uncle Frank posts about chemtrails, then hopefully someone he trusts can point him in a different direction in the comments, and if not, at least the people reading it will see the comments. If Facebook just surfaces this information, you get none of this: click and boom you're in an alternative reality full of lizard people and humans in cosmic battle.
