Pardon my ignorance, where are these wonderful works of art from?

Wish there was more consequences for people who leave the game without resigning. In Lichess there is really no consequences apart from a mild warning

It is annoying, I just stay in the game and collect the points. By rage-quitting I meant quitting the game but leaving the "connection" open.

Damn annoying. Is it just a case of rage- quitting?
