Netizens and fans of girl group Rainbow are expressing their discontent with the ban of the abs, or "bellybutton," dance.  The dance was ruled as  'inappropriate for public broadcast'. Some commented, saying, "I have no idea what the guidelines are for sex appeal," "It's distressing because the members probably practiced so hard," and "If freedom of expression exists, why are there these limitations on choreography?" Yet there were netizens who agreed with the ban."Girl groups are preoccupied with competing in sex appeal," "I'm glad it was banned because it was embarrassing to see," and "I wish that girl groups would hold back on sex appeal." Rainbow's management company also stated that they plan to adjust the choreography for the single "A" to fit guidelines.
