QuoteIt's pretty common on Instagram. When a post suddenly gets a lot of reach, it gets picked up by engagement‑scraper bots and low‑quality throwaway accounts.
These profiles usually have almost no posts or followers, and they leave short, dismissive comments because it makes them look "human" to the algorithm. They're basically testing activity or trying to appear legitimate before being used for spam later.
Nothing to worry about — it's just part of Instagram's bot ecosystem.
