Flaming is directly insulting another member, flame-baiting is making a comment with the intention of getting a flame as a response, and trolling involves starting arguments or upsetting people by posting inflammatory, extraneous, or off-topic messages with the intent of provoking readers into an emotional response or of otherwise disrupting normal on-topic discussion.As far as "cancel folks not cool", some people in the forums sometimes get the impression that it is a democracy here, where you can say anything you want and it has equal value as something someone else says.
