Tell me about it. I had to spend the better part of a day anonymizing my Quora profile, because their concept of private profiles seems like something the founders brought over from their stint at Facebook. Even so, it seems like there is still some history in my EDITS tab that I have no idea how to hide or purge.

Back when I decided to do over my Twitter profile, I used the API to automate the deletion of all my tweets. Any other way would be impossible.
