Honestly - and I genuinely mean this kindly - you are your own worst enemies by finding and commenting on the threads of which you speak. It pushes them into active and so more people pile in and on.
If the clickbaity ones were ignored they would fizzle out. There was one a few days back that really didn't get traction.
Those posters are reeling you guys in! They are enjoying it, too. It doesn't matter what counterarguments or truths you post - they will be used as evidence against you.
I know it is incredibly hard to ignore them- I properly had to train myself to do this during the height of Covid teacher bashing - and I have hidden the FWR board as many of you know.
There is quite an interesting thread running about how MN has got nastier - most posters are in agreement and certain boards do get named.
