I know a couple of people (brothers) who definitely thought that online wasn’t real and they could act without any consequences in their real life. This was back in the 00’s when social media was just catching on. They were absolutely awful to real life friends online and then acted like nothing happened in person. They lost pretty much every friend they had as a result of it. I still don’t talk to either of them. We tried to explain to them multiple times that it was absolutely unacceptable behavior, and they thought it was funny.
