Hey guys, just curious...where do you draw the line with determining if someone is just harassing you, or if it is a legitimate concern? There is someone frequently making nasty comments on my videos, calling me names, etc (I have reported this to youtube and most have been removed). BUT, this person also tracked me down on facebook (that is not affiliated with my youtube account) and started sending me nasty messages there. I just really wonder if I should be concerned- like, what differentiates harassment from stalking?
