Waterfall bot

A term for low effort posting karma-farming bots on reddit, who usually have joined the subreddits of r/waterfall and/or r/meirl. The term was (afaik) first seen in r/PeterExplainstheJoke when it was flooded with an influx of low effort "PEEETAH!" (And other variation) posts with memes that spawn the "Bait or Mental Retardartion"Meme

Post title in r/PeterExplainsTheJoke: PETAHHHHH

Comments: "Waterfall bot" "*an actual explanation*" "Bait or Mental Retardation, Call it"
