In my time at Twitter, representatives of the app stores regularly raised concerns about content available on our platform. On one occasion, a member of an app review team contacted Twitter, saying with consternation that he had searched for "#boobs" in the Twitter app and was presented with … exactly what you'd expect. Another time, on the eve of a major feature release, a reviewer sent screenshots of several days-old tweets containing an English-language racial slur, asking Twitter representatives whether they should be permitted to appear on the service.
Reviewers hint that app approval could be delayed or perhaps even withheld entirely if issues are not resolved to their satisfaction
