I'm pro-experience. Yes I made a new term. I do not mind, actually I prefer things like Prestige hacks. However, when it comes to hacks / glitches that effect the gameplay experience, I'm against it.
Hacking your statistics and levels is one thing, for you're merely making yourself look superior. When someone actually makes themselves superior in-game using something like aim-bot, that immediately destroys the gameplay value.
Hopefully this will never be found on the Playstation 3 for this title or any other future title. Otherwise I'll be transferring to Xbox Live where things are frequently done to prevent said things.
