Use your own head, please. If ed-cons, or god knows who, are going to notify the bad guys it's going to be as soon as they see a prisoner reaching a computer, and transmitting help pleas.
They're not going to be fine with that UNLESS there's CONFIRMATION the person's being helped. If you want to keep this person safe, delete the avatar sig and material denoting her local, (until she's safe, then put it back up) otherwise just stopping short of announcing that people are interveneing doesn't make a difference.
