Making online impersonation unlawful

Arizona is set to introduce legislation that makes it unlawful to use another's name online. The worry here is that parody accounts of celebrities and public figures may be curbed by this legislation. However, under US law, a defence to defamation is the first amendment which guarantees that free speech is protected under US constitution. What is not protected under the first amendment is criminal action that seeks to harm, defraud, intimidate or threaten others through spooling emails, text or other devious motive in the online space.  Many other state have similar legislation, namely California, New York and Texas, and this trend should expand as online frauds and identify theft become more serious  driving up insurance rates and curbing confidence in the economy which increasingly depends on the internet and the cloud.
