Cookies are used generally in tracking in order to identify a user that have been already tracked. If you use only an IP database to identify certain surfer, you may find yourself in trouble with AOL users. Additionally having a cookie set will save the server time to check the MySQL database for entries from that IP address. Cookies are a must when creating advanced tracking systems and rejecting a site just for that sounds meaningless to me, not to mention that cookies are no harm to the surfer. If his/hers browser is not accepting cookies - that's the surfer's decision and we can't do anything about it, but beeing rejected from the reviewer... I just don't see a proper reason for that.
I don't want to offend anybody, but I think that people are generally rejecting sites with cookies, just because they don't understand what the cookie is and are affraid that they cause harm to the surfer. I personally use cookies on each and every of my sites.
