apparently you have to e-mail privacy@quora.com to get your account deleted completely. That in itself is reason to delete your account btw. It speaks volumes of their regard for users and their privacy.
Fun fact: There's no way to get a list of your anonymous answers on Quora. They don't show up on your profile at all. All you can really do is browse through your list of followed questions and manually check each one to see if you responded anonymously.
It's this kind of BS that makes me create fake facebook or twitter accounts to log on shady sites like Quora.
It was non-obvious as to whom I needed to contact... Ill try that email as well.
EDIT: Done.
