Facebook Ad Library API had “major bugs” during EU elections

"“Our documentation of the broken API provides Facebook [with] a clear roadmap to make the necessary improvements to deliver a functioning and useful API,” said Marshall Erwin, senior director of trust & security at Mozilla.

“There are no excuses. Important elections are expected to take place almost every month around the globe until the end of the year. We need an API that actually helps – not hinders – researchers and journalists uncover who is buying ads, the way these ads are being targeted and to whom they’re being served. We need Facebook to be better.”"
