How is that Apple's problem or my problem or anyone's problem but your technologically challenged aunt? You say it's accidental but all I see is blatant negligence on the part of your aunt for not locking down the computer with filtering software or at least checking the site on her own before taking the kids there. If she doesn't know how computers work or what's on the Internet then she should either take a class herself or stop teaching concepts she scarcely understands herself. If parents and teachers want more customized control options for Safari I'm all for it, but when they try to control what other adults can install on their own phones it's time for them to chill out and stop trying to turn the whole world into Disney World.
With stuff like this where it's just a difference between a .com and .gov, it's easy for some people to mess up. How often do you go to .com sites versus .gov?
Besides, she's not in control of the filter. Her district's techs handle what goes through. Plus, there's no perfect filter. You either let bad stuff through, or block legitimate sites. What if a kid wanted to do research on recipes that have chicken breasts in them or something about breast cancer? I've heard of filters that block those, yet allow websites that have some weird, obscure phrase about sex or even a innocent phrase like whitehouse.com, through. There's no perfect, easy way to block web sites. Considering there are 2^32 or more than 4 billion IPv4 addresses out there, while not all have websites, a lot do & that's a lot of websites you have to go through.
I have never been able to understand how people can be offended by statements not directly targeted at them or at least statements indirectly about them, like racial slurs and the like.
It might not be directed at them, but maybe about someone some group he/she cares about. Plus, some might still just find it rude. Are you saying that you wouldn't mind it if someone said to you "You know, all people of such & such a race look the same to me & are retarded" wouldn't offend you?
