My policy for any use of photos of our kids on my blog (which is mostly my projects, but occasionally includes triplogs, and as my kids are getting older, they show up a bit more often in builds) is simple: My wife and I both have to be entirely OK with any photos of them that I use - and I typically will use hand photos, or photos from the rear if they're helping with something. It's only very occasionally that you actually see faces, and that's going to be something like an interesting place we were as a family. Said photos are almost always a landscape shot with us in them.

Our house, our rules. When they're old enough to be interacting with the internet on their own, I intend to apply the same rules - and we run a limited tech household anyway. Electronics don't go in rooms, and we've deliberately set things up so that the house computer is visible when in use, etc.

"Oh, lulz, my daughter has a YouTube channel of her being a cute enough preteen to have 1000 subscribers without me knowing about it" would be well beyond the scope of reasonable, and in addition to having supervised-only internet use for quite a long while, I would supervise the removal of the channel. That's just not acceptable, in any way.

If my kids want to publish things to the internet (and I hope they will), that's fine - it just has to go through us as parents first, at least until a regular trend of good judgement is demonstrated, and we get access to whatever is being published as well.

I would feel conflicted as well. On the one hand, I would be happy to see someone work hard to build something they're interested in. On the other hand, I would feel nervous about all them getting exposed to the grossness of the internet.

His description of the content didn’t encourage me :(

If it was about hobbies or something I might feel differently.
