I clicked on a Dropbox referral link from a random user on one of the SE sites. Following through with the installation, I couldn't find any reference to who the user was that shared the referral. I'm curious if my information too is hidden from them or if they have access to it.Is it possible:for you to know who (userid/email/username) the referrer is?for the referrer to know who you are?
Can a username be inferred from a Dropbox referral?

Your referrer can see your email associated with the account in the history of bonus space (requires login to your account).
