XP cheats available?

Is there a way people get max level and all unlocks through downloaded cheats or modded servers?

I see lots of level 70 players. I grinded my way there back when MW2 originally came out, but I really don't want to do it again. I'd love to join a modded server or download a basic max level cheat, but I haven't found anything yet.

Are XP cheats or modded XP servers available?
