It’s a leak in the Twitter Android app signup flow: https://hackerone.com/reports/1439026 https://hackerone.com/reports/1439026 Not sure if iOS is also affected, thread doesn’t say, but the API doesn’t look Android-specific. Leak was there for more than half a year. Unless you believe Twitter is dying and few people are signing up, I fail to see how you can characterize that as an obscure, low traffic endpoint. Edit: On careful reading, it’s actually the onboarding flow, so even if you already have an account you should still hit it when starting to use the app for the first time.
