Russia has no formal ratings board and no games have been banned in Russia due to excessive violence, nudity, negative portrayal of people of Russia or expression of religious views of any kind because of freedom of speech guaranteed by the Constitution of Russia. Media in America and Europe have falsely reported that Call of Duty: Modern Warfare 2, which features a storyline in which Russian "ultranationalists" take control of the country and invade the United States, was banned in Russia. Activision called these reports 'erroneous'.[31] The Russian version of this game was edited by removing the optional level (the player is given the option to skip the level at any time) "No Russian" where the player is given the option to shoot Russian civilians in an airport.

No, but it might be banned in areas in the middle east like Iran.
no
you can't get banned
No it is not even close to a game that would be banned in England
Cheating can get you banned, but not everyone who cheats is banned
Yes, my friend was only banned for a day though.
Don't cheat, play for fun.
Most likely.
It is something that can get you banned
It's likely that neither you or the person modding will get banned, most of Activision's attention is on Modern Warfare 3 right now, but if they were to find out, you would not get banned, only the person modding.
you can't you will get banned straight away
I believe that it is legal in Russia. It is not legal in the UK though and other countries as well.
