Thanks a lot for this very clever comment my friend.
I think that what you point out is indeed true. I think that it is possible to make out comments where people actually read the post from others. The ones that put dumb comments can simply be ignored.
What is different from steem to a normal blog is that there is not one clear author and one reader. The roles are often interchanged and this asks for new tools.
Did you check this post:

Maybe this could provide an answer.
Best regards
