If you keep receiving errors such as ‘Password is too easy to crack’ or ‘Username is taken’ while you are sure that the password is as complicated as you could think of and the username is as unique as it can be, it may also indicate that the country (detected by your IP address) where you visit POF.com from is blacklisted by POF, thus, registration is not allowed.
