NAFO / Shiba Inu
NAFO (North Atlantic Fellas Organization) is an internet group engaged in information warfare with Russian propaganda. According to its Wikipedia page (linked below), the group began when Kamil Dyszewski began adding images of a Shiba Inu dog (itself a reference to the well-known “Doge” memes) into photos from Ukraine. Since then, the group has ballooned in size and is decentralized in nature. Members create memes of various types, and the Shiba Inu dog is something akin to a watermark that identifies the image as coming from the organization.
