My meaning was along the lines of family dynamics. Teenager starts acting out at school not because they're a bad kid but because their is some unhealthy dynamic in the school or home environment. The kid's behavior is just a symptom of something unacknowledged and in that case the kid is the healthy one bringing attention to the problem. Pain is your body telling you something needs attention.

Mild trolling and shitposting is mostly harmless and perhaps an appropriate response to being very online and maybe a measure of the health of an online community.

One of the big problems though is that trolling and shitposting can easily be weaponized into coordinated harassment on ideological grounds (gamergate, cancelling, etc) which can be construed as a symptom of the current culture war and perhaps social media companies should pay more attention to the problem.
