Jack: awww what's wrong?
Suzi: blah blah blah drama drama drama
Jack: It's alright! <3
Suzi was not upset, only wanted people to acknowledge her. She is Internet Trolling.
Joe: People can be such assholes!
Paula: Is it me?
Joe: No <3
In this case Paula is internet trolling. She had no reason to think it was her, she just wanted Joe to acknowledge her.
