Good vs bad posts could be discerned just by looking at total likes, the way it is on facebook.
Preferably also sorted by the number of total likes. Otherwise the only difference between a comment with 1 upvote and 15 upvotes is a single character on screen that requires some attention to even notice.
Actual spam could just be reported rather than downvoted
There are some kinds of behavior which in my opinion should be actively discouraged, besides spam. Stubborn stupidity, or verbal aggressivity towards other debaters. It would be nice to have a mechanism to do something about them, preferably without getting moderators involved. But maybe those could also be flagged, and maybe moderators should have a way to attach a warning to the comment without removing it completely. (I imagine a red text saying “this comment is unnecessarily rude”, which would also effectively halve the number of likes for the purpose of comment sorting.)
