Social networks, just like in real life, can be useful if you find yourself in an environment that is more educated and at the same time extremely intelligent than you. You are developing.
But in the case of a well-educated person, you end up among the rednecks in 99% of cases, one way or another, and in the end you receive a psychological blow from them, just as in life.
It's all about intrigue and the search for profit, the search for a victim on which you can psychologically unload.
Most of the population is not a critical thinker and does not have their own meaningful, thoughtful and rational point of view based on critical thinking. This part of the population, as in real life, flocks to the herd seeking protection in it, but most often finds dependence.
People are looking for shepherds or victims. And very rarely do they find real support from real altruists with much more life experience than they have. Because your personal problems are of no interest to anyone in the herd, everyone is climbing over other people's heads.
Children under 16 years old have nothing to do on social networks and they need to be legally removed from there. Personally, I would ban the appearance there (in their current crazy form, where the filthy censors of the owners of these networks are formally exempt from liability in the USA under the 230 law, but at the same time trample on the rights to free expression of opinions, thereby violating the 230 law initially for their own private benefit public field) and the population up to approximately 25 years of age. When people in general already have some life experience of independent existence and responsibility.
