Just don't. And if you have, close your account. (Not that it would have helped, it sounds like Quora "helpfully" retained user data for you "in case you wanted to reactivate your account", and that all got popped too...)
As I've said, I use for marketing purposes, I don't personally need it. But I need it to make money. I understand that I can find a different service, but that fact I already know. I'm looking for some new ideas.
