No.

Yes. Any modding of the game, no matter what game type you are playing, can get you banned on an online account. This does not include getting out of maps/glitches in system.
The 'Elevator' glitches have been patched. You can find a new way, but I guarantee you will get banned by me or Robert Bowling. Source: I'm an Activision PlayStation Network Community Manager
You cant if you see stuff like that on youtube.com they are using glitches that can banned you forever
the models used to shoot farther but they patched it.

You can get banned for using a lag switch. I reccomend playing the game clean, anyone can cheat.
