Web scraping gets blocked when traffic looks automated or inconsistent. Weak headers, missing cookies, unstable sessions, poor IP reputation, fast request rates, and careless proxy rotation can all trigger blocks. Reliable scraping depends on consistent request behavior, session-aware routing, controlled pacing, and treating blocks as diagnostic feedback.
