What % of the userbase is "Twitter cesspools" and how do you define that? What exactly is a "Twitter cesspool"? Viewpoints that don't align with yours? Radical politics?
Is Twitter the platform of giving the 10-20% most fringed members of both political parties a voice? Why does what they post get "upvoted/liked/retweeted" enough to the point where it gets visibility instead of being drowned out? What kind of content are they posting exactly that is "ok" to not be removed by moderation policies, but you define it as "cesspool" material?
