I found this link on tumblr, this person on twitter is basically constantly insulting Jared and wishing for his death and also they hit up other celebs/SPN actors to tell them the same things!
https://twitter.com/#!/KristyHobbs We need to get them banned or something. >.<
This is bullying, and it's not okay no matter who the person being bullied is.
*Update*
The troll has been removed. =)
