Liking YTtalk
well im a little late here but 3 things can be done 1:ignore them! if you don't fed them your anger and upset they will move on fast because you are "not good sport" for them. 2 block them! they can no longer leave offensive comments on your channel nor message you anymore. 3 report them! if they are really harrasing you and making your life a misery on youtube report them to youtube itself and they will deal with them (hopefully) i hope this helped you. all the best and stay strong.
