KBS is a public TV station and has a reputation of banning songs (lyrics) and dance moves to make their show (MuBank) more family friendly.
Here are some songs from female groups that were forced to change their choreography:
Girl's Day - Something (They changed this in their 4th live)
Dal Shabet - BBB (the hand position changed slightly)
AoA - Miniskirt (miniskirts were pre-unzipped)
Rainbow BLAXX - Cha Cha (these two moves were altered)
Stellar - Marionette (the butt scratching changed everywhere, this move changed only in KBS)
Sunmi - Full Moon (no legs :( )
Hyomin - Nice Body (Hyomin shows us her face)
EXID - Up&Down (they use a new performance version)
Hello Venus - Wigglewiggle (no shirt lifts (maybe this isn't a KBS thing but well)
Gain - Paradise Lost (the whole choreography changed but these are the main points)
I don't complain though because KBS translates all their shows.
