> niche echo chambers
Letting every sub have it’s own moderators with nearly free-reign is a big part of the problem.
Not density, Absorbablity.
Even 1 headline, as outlandish as it may be, if it is read it can influence a user.
Crucially there are some ideas/content that will just get through filters, no matter how thin it’s presence.
It's basically a tradeoff between visibility to the public and density of toxic content.
