Re: It only makes it easier to crack...

Increasing the delay between attempts can be done in one of two ways. The first is to only track by IP address (i.e. if the username + IP address is the same then delay on each failed attempt) in which case a bot farm can be used easily enough to circumvent that. If you don't factor in the IP address and delay on EACH failed attempt then you're opening yourself up for DoS attacks, preventing people from being able to log in.
