When I play a game against a person and they play well, have a good attitude, thank me for the game, I wish I had a way to add a mark for positive reputation for a person. The same goes for people who rage quit, or are very impatient, I wish I had a way to a negative reputation. Just a + or - that could be clicked and then you could see the aggregate reputation on a person.
I think this feature would help to encourage a positive atmosphere within lichess.
I can see that getting heavily abused after losing. You always have to worry if you flag your opponent in a lost position.
Some people think they are entitled to a rematch, which they are not. Some people think they are entitled to chat, which they are not. Some people think they are entitled to a draw, a win or whatnot...
I can already see the chat: draw or down-vote!
Also, this probably wouldn't really help, as you usually don't pick your opponent yourself. So it could make things only worse because people than start to abort games against the "bad" guys.
It's funny how often people forget that a system that allows them to classify others as "good guys" or "bad guys" also allows others to classify them... including those "bad guys".
