There are laws and twitter policies against this sort of thing:

Barr’s posting of the correct Florida address of Robert and Gladys Zimmerman came at the same time Spike Lee was issuing an apology for erroneously disseminating a tweet that purportedly contained the home address of George Zimmerman, who last month killed teenager Trayvon Martin.

But while Barr deleted her original posting, the Zimmermans’s address remains in messages in her Twitter stream. Barr’s original tweet was a retweet of a post by a new Twitter user who appears devoted to disseminating the Zimmermans’s address and phone number, as well as contact information for Joseph Oliver, who has made numerous TV appearances in support of Zimmerman, a friend and former coworker.

Still, the entertainer left open the possibility that she would again circulate the Seminole County address of Zimmerman’s parents. “If Zimmerman isn’t arrested I’ll rt his address again.” She added, “maybe go 2 his house myself.”

And do what, screech the National Anthem at them? Threaten another attempt at an awful sitcom?

Notice that line about Joseph Oliver? The only thing he has done is try to cool heads in what is fast becoming the second O. J. fiasco. But twitter seems be content to allow Oliver to come under threat too.

Twitter has a responsibility to crack down on the use of its service to commit cyber bullying and cyber stalking. Why aren’t they taking action?
