Well, If you connect to a match where one person is using a mod that gives only himself things like godmode, like the rape mod House posted, I count that as a hack/cheat, not a mod, even if it's done thru modding.
In that case, I agree, at some times (certain hours) at least 1 out of 2 servers has cheaters in them, and it's facking annoying.
Connecting to a real modded server, be it XP lobby, simple low gravity + unlimitedammo and whatnot, or 'real' mods like Avp, TI, gungame, etc rarely happens. To me at least.
Certainly not 9/10.
In legit MW2, which I play since release, I have maybe connected to a maximum of 5 lobbies that were modded. (all were XP/unlock lobbies and/or low grav)
I can however not count the amount of times I connected to a match with cheater(s) in it..
