Unless the victim doesn't care about what they're doing to them. many people choose to ignore the person trying to bully them all the time. The bully will keep trying and trying to succeed at what they're trying to do.
Even when the victim ignores them it works or doesn't sometimes they block them or report them and it doesn't work because they make a different account.But as long as the victim ignores it and reads the comment before talking to them that could keep it from happening.
