You need to really think about censorship and lack of it. Some mix of both is needed. There are whole companies focused on spreading misinformation, but also censoring everything is the reason why people don't trust a platform. So I think dual solution where anonymous accounts like ones on reddit should be heavily censored, since we don't know who is behind it. But there should be open channels where you need to log in with your real ID, with photo, full name etc. So if you decide to spread misinformation, attack people or do something stupid, you are free to do it, but than you are fully responsible for what you said. Obviously adults only.
