Some people think that , and push buttons because they think nothing will happen to them because they are typing and not face to face. Sorry, but when people wanna talk shit about someone and get personal , or post personal info about someone without their consent, it's game on.
I paid someone a visit once because they had the same "it's just the internet" attitude with me. He didn't have much to say when I knocked in his door to call his bluff. He's lucky his son was there and I didn't knock his teeth down his throat
