Problem with stake is they allowed negative trust user to join on their campaign if they changed their rules to make it more stricter to the user who got bad status in this forum maybe it could lessen the spam happening on this forum.
Maybe they need to change some of their rules so that they can fit in the taste of majority.
I don't understand what is the connection between Negative feedback and spam?

Maybe you can see neutral feedback if they are making too many spam posts but giving negative for someone who posts spam is against the DT system and no one is doing so making any change in that rule won't make any change at all about the topic we are discussing here.
But looking at the spreadsheet not many users are making above 35 posts which is really manageable and can be high quality as well.
