To be honest, it does not happen only here in the forum. Not sure about other schools around the world but here in my country, they don't teach that.

I remember back in my high school days when one of my former friends just decided to speedrun their essays by copy-pasting from random articles online and they just tend to get away with it. Oh and yeah, he got A for that. Freaking A from a work with no effort. I was naive that time that is why I can't talk about it.
