Advocates several time for someone's death (not to mention that the method of death they were advocating for that someone is a very brutal, traumatizing, and horrible way to go) numerous times and tells them to delete their account numerous times instead of using the block button, then goes "b-b-b-but- but- i-i was just JOKING!!!!🥺🥺🥺" and accuses the user whos death they advocated for of harassing them for simply commenting on their images which are public and anyone is free to comment on. What type of behavior is this?
