I've been in IT for 30+ years and can attest to the need for better P/W rules due to the reasons Kevin mentions. Also, depending on the operating type and version, some of the current O/S's have minimal password rules setup as their default which includes ageing and rule sets for string structure (ex: upper case, length, numerics). You would be very surprised how many automated login attempt 'bots are out there that will systematically work through username and passwords in an attempt to gain unauthorized access. That is why most sites will allow only X number of login attempts before either locking your account or setting an account login timeout to so many minutes or hours. As for camaros.net, I'm not sure how their logins are captive in regards to shell escaping to get to an O/S prompt, if at all. I'm sure that is confidential information.
Hopefully camaros.net is using some form of UNIX or Linux instead of WinBlows
