Flamebait refers to a message posted to an
Internet discussion group, such as a
newsgroup or a [mailing list]
?, with the intent of provoking an angry response (a "
flame"). Various motives or explanations can be sought for this puzzling behavior; from a commonsense point of view, the practice seems usually to be a cry for attention.
Flamebaiting and flaming are an interesting psycho-social phenomenon that no doubt will be exhaustively studied within the next decades as the Internet matures.
