Handle it carefully is good advice. But the rest of post suggests poster has never been in a relationship / doesn't know any human women, if they believe every single workplace relationship will result in at least a POSH complaint.
That doesn't work. Borderline trollish comments can get tagged and unpublished. Ones that actively detail a discussion, are hateful, abusive, illegal or have been reported as potentially defamatory, should not be readable anymore at all. What's there to disagree on?
It's actually very simpl. Fact of the matter is: the ONLY reason LI is being kept running is to be helpful to lawyers, provide a bit of entertainment and community. If you don't agree with those aims and think LI should be a radical experiment in free speech that fights off legal cases for not moderating anonymous comments that have been reported, please seek or start another platform.
We're moderating what's always been moderated: stuff that's reported as untrue, unprovable, potentially defamatory, toxic, abusive and trollish. Perhaps more readers are reporting such comments or more readers perhaps are posting these. Suffice it to say, it's a deliberate decision made for good reason, and your post provides no arguments or reasons to do otherwise.
1. Put away your phone or electric devices when you sleep, and don't check LI / social media first thing in morning / when you go to bed.
2. Read a book or watch a good movie or TV show?
3. Figure out what itch LI scratches. Is it boredom, or anxiety about career, etc? See if you can tackle those another way.
Google for online or social media addiction or watch some videos, some might have some useful other tips or advice.
