PostGhost’s tweet collection was too broad for Twitter’s liking.
While Twitter isn’t completely opposed to third-party sites preserving tweets, it has its limits: the social network has effectively shut down PostGhost, a days-old service that archived the tweets of verified users with “tens of thousands” of followers. Twitter would only tell us that the site was violating its developer tool policies, such as honoring content as it’s displayed on Twitter proper. However, you could also argue that it just wasn’t as discriminating as Politwoops is now — it was targeting anyone with a blue checkmark.
