I don't know if this works for anyone other than our family but when we were raising our kids we solved this by the simple of expedient that gaming and computer use was done with us as parents present. Full stop. It was not a solo activity for our kids. We could directly view everything they were doing online the entire time.
Advice like this only works for specific age ranges. When I was a kid I had a friend whose parents, or mom rather, went to similar lengths to ensure all gaming was monitored closely by her. She would turn the game console off if she saw anything she decided was not to her liking. This was all fair when we were 7-8, but she insisted on doing it well into his teenage years. This level of extreme control and micromanage…
Also you have to consider the ramifications of such behavior if that gets public, I mean could possibly be the source of bullying and what not.
As a child we were de incentivized to playing games with the computer. The schema was:
A) computer you can have, because is useful beyond playing, consoles, no way. Forget it “that is stupidizing BS”
B) No money for games. Other SW would be bought, but rarely games.
That moved us to start spending time with other things in the computer, like programming our own games.
Of course today that is all difficult to impossible, by design, without ostracizing the kids.
