I've read somehere, I don't remember where... might be local board
they're saying risk on freebit account, changing email and/or payout address might get it locked
I'm not sure whether just because of that or something else that might trigger it

is freebit account transfer/sale prohibited?
I think the thread was talking about account selling & risk of banned/locked if changing email
not saying I bought my account, I created it myself long ago and want to change email now
but were afraid will raise a flag due the fact that faq mentioned:

          By clicking on the button that says PROFILE in the top menu. 
          You will be able to change your email address only if the email 
          that is currently attached to your account is invalid or it is bouncing our emails back.
