An Instagram user who runs a repost account, meaning that they do not personally create any chalk-eating videos, told Motherboard in an Instagram direct message that they believe most people who make "chalk-eating" videos do not actually eat the chalk (The user asked that Motherboard withhold their account handle because certain members of the chalk-eating ASMR community have been bullied.)
ASMR is usually precipitated by stimuli referred to as 'triggers'. ASMR triggers, which are most commonly auditory and visual, may be encountered through the interpersonal interactions of daily life. Additionally, ASMR is often triggered by exposure to specific audio and video. Such media may be specially made with the specific purpose of triggering ASMR or originally created for other purposes and later discovered to be effective as a trigger of the experience.
