13 /= 5 (numeral cited in the parent comment). I stated in another comment that I think 8th grade (aka 13) is the appropriate time for internet exposure precisely because it's when I think kids can possibly be exposed to this sort of thing and have it have less of a chance of it being damaging. I think the fact that you cited some of the more severe dangers a younger friend at 9yr faced further illustrates the point. Kids should not have access to the internet until they have access to sufficient information literacy and critical reasoning skills.
