I use your comment
The same way you [prevent] yourself from [engaging] with trolls. Be alert, [pay attention], when you get the [sense] you are engaging in [fake content] (or with a troll) then [disengage].
The same way you [prohibit] yourself from [involving] with trolls. Be alert, [take note], when you get the [hunch] you are engaging in [fluff] (or with a troll) then [withdrawal].
That's enough data to encode.
Does even matter? As long as the replies are sufficiently relevant, and I am completely blinded.
This gets you in the habit of spotting slop, and sends signals to slop posters and HN moderation algorithms. If enough of us do this, we can clean up the joint.
