It's hard for me to see things like Ice Poseidon's stream as media or entertainment, really. If this is a predictable consequence of streaming which restaurant he's going to, then Denino is basically just ruining someone's day (and possibly much more) because he thinks he'll make money off of it. Nor is this anywhere near the bottom of the pile. Trollstation has picked up jail time over three different 'pranks' - a bomb threat, a fake armed robbery, and a fake kidnapping. Which puts "fire in a crowded theater" to shame, honestly - waving a fake gun around specifically to frighten people isn't even something that gets considered in most free speech debates, and rightly so. (I shudder to think how that prank might have ended in the US.)
My favorite example, though, is still RossCreations. Whose idea of a prank was... taking down stopsigns. Just that, going to an intersection and taking away stopsigns so maybe some people would get in a car accident. He was apparently charged with felony grand theft (stop signs aren't cheap), but I'm a bit surprised no one threw in a public endangerment charge alongside it.
I guess I don't understand how we got here. I know people doing stupid stuff and misjudging pranks is nothing new, this isn't a "kids these days" complaint, but where did people get the idea that "it's for my channel" changes the ethics or legality of things they know will go wrong?
