I'm kinda in this camp for the most part because if someone is stupid enough to do any fucking internet "challenge" then they're going to find any number of ways to exit this planet sooner or later.
That said, its usually someone's kid that ends up hurt because of this shit, so for that reason alone, I'm ok with the reminders to kids to not to be fucking idiots just to prove you can join in the next viral goat rodeo.
