Why I speak sometimes about "Glitch using" and/ or "Bug using"? ;)

Hello everyone. I'd like to start an open and honest discussion about why I (and other players...) sometimes talk about exploiting bugs/glitches in the game chat and why we don't really like it. You know, playing games is supposed to be fun, right? But if someone, especially someone "deliberately" exploits bugs or glitches in the game to gain a perceived "advantage" over all the other players - is that really "fair play"? Or wouldn't it be better to report such bugs and glitches to the admins so they could potentially fix them? Wouldn't that be much better for the player community? What do you think?
