The child in OP sounds to me like she thought she was making a bad-taste joke in a private forum, and was shocked when it promptly led to an entanglement with an unfeeling system who was looking over her shoulder. I’ve never threatened to kill anyone in my work DMs, but I’ve definitely written stuff that I wouldn’t post in public threads. I think we all to some degree use these “private” systems this way until it burns us, only then do we adjust. Privacy is much more a feeling than a technical reality.
In that sense, it isn’t “normal”, it’s just “something that’s happening in theory but eh maybe it only affects scary people or whatever idk”. I feel like this tolerance we’re developing for outside forces invading “private” spaces, nominally for these loose justifications of harm reduction, will be what _actually does_ make it normal.
Once it’s truly normal, and people think it’s what keeps them safe from mass shootings or whatever, it will be too late to get rid of it. I think fear and normalcy will motivate its spread to places beyond school chat platforms and Snapchat.
