Evaluates reporting-system analytics for valid reports and misuse detection in moderation workflows. Strong answers define distinct reported-user share, write SQL for valid reports, and detect abusive reporters through frequency, hit-rate, burst, and coordination metrics.
Scenario: Content‑reporting tools can be gamed. Calculate valid‑report ratios and detect users spamming false reports using SQL‑friendly metrics.
Question 1: Compute the share of reported users with at least one valid report. (Hint: numerator/denominator definition, deduping)
Question 2: How would you detect misuse of the reporting function? Provide metrics and SQL. (Hint: report frequency vs hit‑rate)
