I've been on MN for around 15 years. I used to see it as supportive and some parts of it still are.
However, I think MNHQ are not on top of trolls and I also wonder if they allow 'Trending' (but fake) threads to continue as (being cynical) it brings more traffic/clicks to support their advertisers.
I've reported thread that look fake (and many posters were saying the same on them) but it's rare for action to be taken.
I admit I shouldn't be so invested but there were threads asking for 'help' with family type dramas and health, and I got sucked in trying to be supportive.
