A friend of mine gave away her Facebook password to someone whom she believes has used her Facebook account to harass others. She is now in trouble and we are trying to help her out.
The idea would be to obtain the IP used by her account to post those messages from Facebook's logs, then move from there.
The question, then, is how to contact Facebook to obtain this information. All forms from their help center that allow you to submit information seem to be (I presume) seldom-looked at, often with specific disclaimers that they will not respond to any information posted there. I would like a way to get in touch with someone for a fairly low-latency exchange, as time is a factor.
