they actually thought they had addressed the cheating issue initially by making any modified pk3 files unusable on servers that ran "pure"...but this also makes it impossible to place user maps in your main folder and join a pure server (as well as the issue of not being able to place more than 4 or 5 maps at a time in your main , and still run stable ) ! as far as bunny hopping , they should make jumping more than 2-3 times slow your running speed down to a crawl as if exhausted...and the iron site should be tweaked to NOT slow you down so much
