She deleted that account with all posts. I heard that some guys from higher grade told her, that they are going to police if she is not stopping.
And about lawyers, it is kinda hard with that in Lithuania. You need a lot of money and time to do that kind of things. Still, even if nobody knows who she is im glad that this "gossiping" finally stopped.

I am from Lithuania, the girl is from my school. You can check my IP if you want. Maybe you guys know how can i contact facebook so that they would tell me who she is? Because i actually can't find such option 

Well, i want to do that as a anonim. I am not searching for enemies ,but i have my rights to know.

And there is actually no other way?

Hey guys, i have a big problem here.
There is a girl or  boy in facebook that named herself by a name of "gossip girl" she with this name is gossiping about many people in our school, somethings are real some are not but all of them are private. I want to find out who she is. With a little google'ing and stuff i managed her to send me an email, so that i could get her IP. Now what i need to know is how can i find what other facebook accounts she logs in to while using that IP. Ip tracers doesn't work here because it doesn't show exact adress. Can anyone help me.
This is her IP: 78.60.105.65
