what is so hard to teach children not to e-messaging with strangers just like not to snail-mailing with strangers? also the parents should be able to join the conversation just like in the analogue world. call me backward but i dont want to outsource parenting neither to government nor to remote businneses.
In analogue world, shops and pubs are responsible for not giving kids alcohol, porn, gambling access and whatever else. In an analogue world, parents are not expected to do perfect surveillance every minute of kids lives.
Also, parents have in fact full control of snail mail.
