Harassment laws should be enforced on twitter as much as anywhere else.
"Generally, criminal harassment entails intentionally targeting someone else with behavior that is meant to alarm, annoy, torment or terrorize them. Not all petty annoyances constitute harassment. Instead, most state laws require that the behavior cause a credible threat to the person's safety or their family's safety. - See more at: http://criminal.findlaw.com/criminal-charges/harassment.html...
"I'm going to rape/kill/etc you" should probably end up with you in front of a prosecutor in many states.
