I know many people share your view if social media platform x allows content y, then it will be reduced to anarchy. I never understood that. Reddit used to allow some pretty insane sub-reddits, but I never knew that until it was on the news that they banned them. I used the platform daily and only looked at what interested me. Vegetarians and Keto(atarians?) both go to the same grocery stores. They just pick the part that works for them and don't worry about the rest. Could you explain how you would imagine that Twitter "could quickly devolve into a scarychan-style sewer?"
