What was really weird was when she found her way onto a "chicken site" & started seeking advice on how to impress her boyfriend. That sent up red flags for me from the get-go. Sounds to me like a kid with too much time on her hands, in an unsupervised environment, looking to stir up trouble for something to do & tell her buddies about.
Probably the best approach, should something similar ever happen again, would be to simply flag them w/o even bothering to reply to them.
I did that on the last round.
