>The seller told me they scraped the data using the same set of weaknesses in Birdsite APIs that allowed the scraping (and publishing) early this year of profile data on 5.4M Twitter users.

Sigh... So many of the massive social media leaks are just people taking advantage of their publicly documented APIs.

I fear more services will stop providing public APIs and maybe even use constantly changing obfuscation like Snapchat and TikTok to make it harder to use their internal APIs.
