The bait usually justifies, but does not explicitly urge, the replication of a meme-complex. Also called the reward co-meme .
Memes evolve in competition for niches in the belief-space of individuals and societies.
Any attempt to hinder the spread of a meme by eliminating its vectors. Hence, censorship is analogous to attempts to halt diseases by spraying insecticides. Censorship can never fully kill off an offensive meme, and may actually help to promote the meme's most virulent strain, while killing off milder forms. Also called a symmeme. Currently without human hosts.
