boxes removes bridgers. if you play on an old xbox, you can hear the new maps load, and thus stay away from modders. if you do this, the only thing that can happen is some random cheating nub could standby you or (incredibly unlikely) you could get old-map modded.
i don't know what this "not allowing user created data online" thing is, but it sounds like it would fall under "manipulation of online play"
if you want me to explain further, please send me a FR or scorpion, in your case, just invite me.
