thats some seriously fucked shit. now with security you should have upper/lowercase letters, numbers, and symbols.
and it woudnt hurt to change your other passwords. people have a tendency to use only one password and email combo, so as its not a huge huge personal threat if your fb gets hacked (well yours was pretty shitty) they can go to your online banking and hack your shit real easy. same with your email, paypal, etc etc.
just some advice that is good for many. this is why i have my financial passwords completely different from any forum, fb, or email passwords.
