CoD+Skins=ban?!

[checkmysix]

Hi Guys
I dont intend to Play on-line BUT I do want to use Third Party skins for
making Machinema Movies and posting on Youtube.
Is this likely to get Me banned,also are these skins detected in my Steam account anyway or ONLY in Multiplayer?
I would also like to add Swastika to Default German Skins and again will I get banned if used
I see that Guys have posted Images and Downloads of their Modded
Skins on this site and was wondering if anyone has had a Ban as a result of this?
Sorry for so many questions BUT better safe than sorry
Regards
Keith
