There is not other way as far as I know. But here is the thing, if you try this it will work.
Log in with your roadblocked accounts until you get to the first roadblock, then login using another browser with your real account and everytime Facebook asks to identify a friend, search that persons name with your real account. This way you can recognize some people faces.
Just try to be as fast as possible. If you don't succed at first you will do after 1,2 tries.
Good luck mate!
