Someone who signs up for a YouTube account so that they can leave mean and insulting comments on other people's videos. An anti-youtuber has no videos themselves and has little or no channel views. Sometimes with subscribers that are from their other fake accounts, or their friends which the anti-youtuber forced them to subscribe to.

Anatidaephobia is defined as a pervasive, irrational fear that one is being watched by a duck. The anatidaephobic individual fears that no matter where they are or what they are doing, a duck watches.

Anatidaephobia is derived from the Greek word "anatidae", meaning ducks, geese or swans and "phobos" meaning fear.

Youtuber whose content predominantly consists of satirizing and commenting other Youtuber's output of videos. The main characteristic of an anti-youtuber is how they subvert Youtuber customs, in a cynical and ironic manner. (i.e. the average Youtuber will tell viewers to "like and subscribe" ; an anti-Youtuber will do it while adding an ironic spin).

A Youtuber that does this while also creating content that isn't focused on another Youtuber can be considered an anti Youtuber. (i.e. iDubbbz and his Content Cop series).
