>Do we agree that showing a 14 year old a picture of a man's gaping asshole is bad?
This is disingenuous. He didn't show them anything; they went looking and found something they didn't want. As they say, you can't go to shit's house and be surprised when shit is home.
>They probably didn't even understand the mechanism
Which is their problem, regretful as it may be. Or more realistically, it's their parents' problem.
>words like "hotlinking" and "bandwidth" and "solution" shouldn't come into play here at all.
That was the problem that started it, so they're absolutely relevant. Pretending that this doesn't matter is willful ignorance. No one was made to view anything.
