I agree with you that self-votes generally hurt the system and the system is flawed. My point is that the majority of the hurt is being caused by bots and people not on your radar.
Also, annual return is extremely important in the crypto world. Everyone is claiming to be a day trader or investor in crypto. They are absolutely looking for a return. You should try to understand that the return drives the motivation of a lot of people on here...you don't have to agree with the behavior, just asking you to recognize it's importance.
