Yeah, this is a big one, and has been a major reason for a lot of recent terrorism (like doxing and sending threatening packages to people’s family and swatting). Without being held liable for their actions, a lot of shitty people feel emboldened to act in ways they would never dare offline. And that’s not even getting into stuff like the grooming tactics of extremist groups online, convincing kids that minorities are why they think their life sucks.
