Soon, the video was being broadcast by television channels.  The girls were praised by the media and given the nickname "bravehearts".  After a second video emerged within a few days, which showed them kicking another boy, the opinions began to shift towards negative.

Later another man came forward and claimed that he had been similarly accused of molestation by the girls and he had to pay to have the charges dropped.
