One who deletes; a person or program that removes or erases something.
From English delete (itself from Latin delere, 'to destroy') with the agent suffix -er (one who performs an action). This is a modern coinage reflecting digital terminology, as 'deleter' became common with the rise of computing.
The word 'deleter' captures something philosophically weird about digital life—you can delete a photo in a millisecond, yet companies keep backups forever, meaning deletion isn't really deletion anymore.
