This is such a difficult problem to solve but I think identity is also very important. When I started out I was using my actual image for my profile but everyone else is using avatars. So I changed to a generic avatar. While these systems aim to increase privacy and free speech they tend to remove skin in the game. Which can make people behave in ways that they would not behave if they had skin in the game. This is what I noticed when it comes to social media platforms, they tend to turn bad as soon as there is no skin in the game.
