1) She is doing something she is not proud of and you are posting it on the net
2) Since it is of a sexual nature, it will tend to attract certain types of unsavory people (not talking about the ppl above, talking about psychos and pervs....ok, well, maybe talking about the people above...KIDDING)
3) You posted her email address in a publicly viewable, searchable, google indexable forum. That invites Cyber stalkers and Spam and could potentially limit future employment options if a potential employer has that email address for her and does a google search.
Way to help her out
