One of the problems shared by many social media platforms, is the "pile on" effect. Someone says something dumb and the entire Internet shows up on their doorstep to mock them.
Twitter has this problem in spades, it's one of the reasons it has a bad reputation for harassment.
As far as I know, there is nothing technically preventing the same problem here in the #fediverse though.
If it became a social norm to just star people who have already responded instead of piling on, that would help.
