Hey guys, just wanted to say thank you for all the ideas I've read here. I could manage to unlock my account combining these infos. It took me a week, but it was a success afterall. I made a mistake with the fake profile though, I've set the friend list as hidden from everyone, so when facebook started to show me random photos with the names, I could not check the friendlist from another profile. What I did instead, I searched for the name in my emails from facebook, when that partiucal person added me, and from the email I could copy their profile's link. Now, many of them are showing photos only for their friends, so the best thing I could do was to check them all quickly, and to see if there is a similar photo. For example, a white blondie guy won't have a name like Rajesh

Sometimes when I searched for the profiles, after the 5th question facebook told me I was too slow, try again. I felt like leave this whole dmned thing, but now I see it's worth trying.
Once more, thank you for all your useful infos!!
P.S: One more thing. To have less problems with profiles in the future, I've added another profile as friend, and only that "person" can see my friends list, but hopefully I won't need it anymore.
