Forgot about this dude
I would tend to agree that parents needs to allow children some mesure of privacy in their online adventures (depending on things like age, maturity and the kind of internet access they have. At some point and if the child isn't acting out in weird concerning ways, you need to trust the education you gave them and that they are gonna take the right decisions)
THAT BEING SAID
1/ This dude is already being quote-rted by someone saying "my parents prevented grooming by reading my dms", proving that snooping can save lives
2/ He is way too invested in the issue, this long meandering thread could have been 3-sentences-long. What are you afraid of, that those parents find you there in the dms?
Maybe his tiger mom traumatized him, idk
