Finsta

a secret or incognito account on the Instagram photo-sharing service

"Finsta," a slang term, is widely accepted as a contraction of "fake" and "Insta" (short for Instagram). … "Fake" here does not refer to the account owner—finstas are real accounts run by real people, not bots—but instead distinguishes the private, and to some extent secret, account from the "real" public-facing one.
