There's a middle ground shockingly and I do think it's roughly why this all came up at once.

"Just parent" isn't easy in an age of large numbers of families having to both work and kids having a computer in their hands at all times.

The "please don't say you're 18 if you aren't" standard has NEVER applied for anything else flagged as adult. If you sell products or allow services to a minor without doing proper checks YOU are responsible as the company if it's found to negligent, to the point you can lose your license.

The thing is, you also don't fucking store every single ID you've ever looked at because that's insane, or if you do, you do it for very short periods of time. If a kid gets a fake ID, fine, that's on the kid so long as the company is doing their best.

It's why an "adult mode" local cred on the machine is probably reasonable? If the kid gets a fake cred, fine, that's on the parents, but at least sites can automatically look for the cred and if not provided just bounce.

As it is ALL the onus is on the family, and there's a fuckload of preying on children (especially economically) that's not supposed to be remotely legal that we've just kicked open the doors to because its "hard" to solve.
