Scenario: Creators often juggle multiple Insta accounts. PMs built a one‑tap switcher but need clarity on identity resolution, behavioural impact, and abuse risk before GA. Design detection signals, interpret experiment anomalies, and advise on launch.

Question 1: For the account switcher, how would you detect multiple accounts for the same person? (Hint: device fingerprint, login cadence, IP linkage)

Question 2: Experiment shows more accounts per user but unchanged time‑spent—why? What data would you pull? (Hint: usage contexts, creator behaviour)

Question 3: Should Meta fully launch the switcher? (Hint: revenue uplift vs complexity, abuse risk)

Question 4: Which segments might dislike the feature and why? (Hint: privacy‑conscious users, shared device scenarios)
