Quora has been hacked.
Note that avoiding the ill effects of breaches like this is an important use case for anonymous cryptocurrencies. If a site only has your throwaway email, then it doesn't matter nearly as much if they get hacked.
"For approximately 100 million Quora users, the following information may have been compromised:
Account information, e.g. name, email address, encrypted (hashed) password, data imported from linked networks when authorized by users
Public content and actions, e.g. questions, answers, comments, upvotes
Non-public content and actions, e.g. answer requests, downvotes, direct messages (note that a low percentage of Quora users have sent or received such messages)
