So I've been mulling replying here.
My thoughts on this get disregarded pretty often, which is vexing, but w/e.
I grew up in a very fundie Christian household.
My parents were abusive (mostly emotionally, but not just). My father is a developer. He did often log things I was doing. And used it for mockery and also to 'prove' I was allowing demons into the house. It was never a 'protectionary' measure in the sense that one might hope.
In my case, yes, it was a very negative thing.
However.
I spent years working in children's forums and games as an administrator and moderator.
I have witnessed grooming, predators, and the ways that kids, unfortunately, do not know how to protect themselves. I also worked in a community at one time wherein LGBT conversation was not allowed because of a very, very bad incident once and where I got special permission to take a conversation off-site to talk with some of our older users about it (because they were understandably upset).
The incident had been wherein a 9-year-old user had asked what a lesbian was. And a group of older girls began bullying her across the site. To a point her mother sued the site.
Now, when I was able to sit down and explain this to these kids, they understood. And they stopped harassing the moderators (because I explained: look, we aren't homophobic, I hate that we can't let you guys discuss this, but please understand that many users here don't understand sexuality at all yet! and we want them to find a healthy outlet for it) and instead became champions for other kids going to school counselors, pastors, their parents, etc., while sending campaign letters to the site's ownership (vs angry emails to us).
Eventually the ban was lifted and these same kids continued to help us keep an eye out for similar behavior. It was heartwarming to see. But it took a long time....... and it took me having to out a coworker as homophobic, sadly.
ANYWAY.
Working on that site and others is why, when I was married and had a stepson, I was keenly aware of his online activities (he was under 10 while I was married). Why I would be if I have kids again.
We had a guy on that one forum known as 'dan.' 'dan' was as pervasive as our troll here. And he was constantly trying to get these kids to engage in cybersex with him. Share their RL locations with him. And he'd masquerade as a teenager.
On other sites, I saw kids gladly share their phone numbers, discuss meetups, etc., within their very first conversation with someone.
And many of them? When caught? Would create a new account and show up to share sites that were adult in nature to 'continue' things.
No, we don't want to stymie kids from exploring their sexuality, identity, etc., but the problem is that so many aren't doing so safely. There is a balance to be struck. If they're openly sharing very personal details right out of the gate or going to unsafe sites: that's a bad thing. That is not safely exploring sexual/identity. That's putting themselves at risk.
We have people here (@Pandora, @mietze) who understand how to educate their kids on how to be safe, how to construct a safe home environment, to where they can monitor their kid's online activities to the right extent while also making their kid feel safe enough to approach them if worried, concerned, scared, etc.
I 100% think parents need to be aware of what their kids are doing online. Do you want to be keylogging or anything? No. But you don't want to just set them up with a personal laptop behind a locked door and never ask any questions.
My parents were abusive, but it went far, far beyond their stalking my online activities. Their inability to make me feel safe began before we had internet access in the home. They never observed my online behavior out of a care about me. They did it out of a desire of control. The two are wildly different.
