[chefsurfing]

Does not seem like a minor thing to me and worthy wanting to leave the system. Emailing them worked for me last week. This behavior reminds me of an early ( now-defunct ) social network which upon a person's registration would attempt a login to their email ( hotmail etc ) using the password ( not encrypted ) that the person used to register on the social network. Upon gaining access to the person's email the system would copy all the email addresses from the archive and begin spamming those users with invitations to the social network. As many naive people do use the same password for many services this attack would often succeed.

Quora ( among others ) seem to be taking advantage of our current naive attitudes about social networking, privacy and sharing. It might seem extreem to compare the email hack to these sharing hacks right now, but I think in time we will come to see that these two infringements have more in common than not.
