Err, you are ALL wrong!
Cracking vBulletin hash's and salts is extremely easy. All you need to know, is the hash format, which is: MD5(MD5(password).salt)

People load a dictionary, set it to dictionary mode, load the user: password:email list, and within seconds, all the easy passwords are cracked.
Leave it an hour or so and the more difficult passwords are cracked. If the rest aren't cracked by the end, changes are they're using an extremely hard password.

Make sure you use a combination of lowercase, higher case, numbers, letters, and special characters when you generating a password:

Example: ()Q@[]4[[!*^Yejfbn f(@344{P}{(*&@
- Virtually impossible to brute & dictionary attack.
