Quick question, have any of you guys either in multi or single player games ever used cheats or exploited glitches in games.

The reason why I ask is that just recently I have been getting back into playing CoD4 online, now I am the first to admit that I am not the greatest but I am also not the worse. However I have been noticing more frequently other players not just with me but on others, that they are using glitches (running out of the map in certain areas, jumping on certain buildings) that sort of thing all to make sure they win a round or a match or whatever. I have asked Activision about this and they gave their standard: "When the game is written, the programmers use cheats, to help them, these are often left in the final production version of the game and cannot be removed.

C'mon guys do you think this is right?
