First of all I would recommend you to do suggestions on musing.io in their Discord Server (https://discord.gg/zMcHDfR).
I read about trustability score for the users just for musing.io (so not depending on the user's reputation). With this users with helpful answers and maybe also good questions should get a higher score than others. I think it would be possible to implement a filter then where you can filter out users with a low trustability score so these senseless questions won't appear in your feed anymore.
Wow... thats an awesome idea, that way, we all (including me) gotta also watch the kind of questions we ask, Just like how we think very well before making a post on steemit. Thanks for the feedback.
