I think I am in a very small group that would like to see more negative feedback and less neutral. I really thing nobody reads the neutral.
Perhaps, it's just me but I have had some people who I told to take a look at this board come back and say "nope, it's a crapfest would rather be on r/CryptoCurrency/ or one of the discord discussions"  Think about how bad we look when things like that are said.

I don't know if there really is a good solution, you want to have an open forum you have to put up with crap posters.
You start aggressively moderating people it annoys a lot of them.
Having users self patrol seems to work to a certain extent, but then you get what we have now which is people who don't like the way others are doing something and think their way is better.
