There was a while there where it was genuinely upsetting to see some of those people. They really didn't understand the difference between pranking a friend that's opted in to the behavior and random people in public, and what's acceptable as a prank in both instances.
I'm sure Jackass had a few misses in this department too, but at least by the time they were famous the public stuff seemed more along the lines that might leave public people that saw it or were unwittingly involved thinking "WTF did I just see" or a story that later they would start with "You wouldn't believe the stupid person I saw today" and if the person realized it was a prank would generally think it was rather funny since it didn't affect them.
Contrast that with youtube "pranksters" of the time when they first started being popular physically assaulting people, or stealing things, or tricking someone into thinking they had lucked out and then making them feel the loss of that when it was shown to be fake as well as humiliating them in front of the world. "Haha you thought that $100 bill was real? Psyche! It's fake, you didn't find anything! Hey everybody, look how sad he looks now. Why are you sad, bro? It's a prank, be happy, the whole world is watching!"
I remember having to very carefully counsel my young son who kept stumbling on them and watching them on why these people weren't being funny, they were being mean, and this wasn't how people should be treated.
