I think she got banned for ICO farming, that concept isn't official yet, but is a bad way to participate in the forum. Too bad for her, she could make some great friends here and learn a lot from the good topics, but in the moment she decided to use the forum to spam for ICO's her account was doomed.

If she will open another account and try it again then i recommend her to be more active in other sections and to join on real discussions, not only ICO spam.
