Trolling 101

Hey everyone! I’m a little lost here—I can't quite wrap my head around what actually counts as trolling on this forum. Is it just one of those subjective things where it depends on who you ask? And honestly, does breaking that rule actually mess with how the whole community runs, or is it just a minor thing? If anyone could throw out some real-world examples of what qualifies as trolling right here on our boards, I’d really appreciate it.
Thanks in advance!
