MW2 Glitched XP lobbies?

Most people who play MW2 know somebody or have seen somebody who is a 10th prestige. Most of these people have obtained this through glitched xp lobbies. If anyone knows someone or is hosting one I would appreciate an invite. My gamertag is I RingRaiders I ^^

I'm almost certain THAT mod(it wasn't a glitch but some modding) has been removed.(though there could still be some way around it, or a new one similar to the minus Xp lobbies now)
