1: the i can guess that the ha$h you get is from a FAKE site which shows some magic for free and then says you need to pay todecode the hash

fb databases are REALLY secured that it is really a very low possibility that this kinda of bug exists
simply there are on any fb hacking tools/software/scripts or ANY automated processes

you just have to do it by yourself and i dont think that this forum is suitable to discuss those kindda things
