Among other sites that are blocked is also reddit.com/r/sex . I cannot understand how preventing children to access educational sex-related materials could be construed as "protecting" them.
I agree that the filters are overly broad, but in fairness /r/sex isn't just about education. There is educational material on that sub, but there is also "adult" content in the strictest sense.
I always viewed these filers as being in place for actual children (age 1 to 11), teenagers (12+) should have them removed. If I had kids I would have no issue with them watching porn (aside from 3G data usage) and I wouldn't want to accidentally stop them from accessing information on sexuality.
I think a lot of parents have this strange idea that if you stop kids getting at the information (or condoms) that that will somehow stop them from having sex (or doing other stuff). But the research and statistics are contrary to that.
Frankly my biggest concern would be so called "sexting" (i.e. sending erotic pictures or video to their teenage love-interest). Which unfortunately only education can combat, there are no workable technological solutions that I am aware of.
