Were you born prior to 1935 grandpa?
that's grandmom son And yes there were computers, etc., but not for the average home user. I mean I remember when color tvs were the big thing to have, ok?
Anyway, yes 10 y/o do go to youtube, they watch things, they upload things. If I had a 10 y/o I would hope that I would be able to keep an eye on what they were doing online.
But something like this, where youtube apparently dropped the ball, opening the way for 4chan or anyone to pull this stunt, well, you can be a great parent and be sitting with your child watching what they watch to monitor them and there's no way for a parent or anyone to be ready for something like this. Yes shut browser immediately. But it shouldn't have happened in the first place.
