In the nicest way possible, it's a fairly basic part of parenting to parent your child.

Nobody is asking parents to be a omnipresent panopticon, but you should absolutely be making use of the tools built into the devices around us to protect your child instead of shirking that responsibility onto the wider world, and relying on the Government to half-arsedly nanny your child for you.

If you don't have the want, or the time to do that, then you aren't ready for one in the first place - and if you do have one, grow up and do the job you signed yourself up for.
