the first amendment doesnt protect you civil suits to harass people. the first amendment protects you from the government. this law allows private individuals to sue private individuals for harm caused deliberately by making public information which is not public. the funny thing here, is that was always true! this "law" just codifies it. thsi illinois law doesnt really change anything. you can always sue someone who does something that harms you, physically, emotionally or financially. what the illinois law really does, imo, is recognize that "doxxing" is a form of harassment ... which has some interesting legal ramifications. which takes us from the civil realm and into the potentially criminal realm. now of course you cant use the doxxing law to charge someone, but it does form an interesting basis for self defence ... ie someone who has doxxed you, has harassed you ... ie they are no longer an innocent third party. the doxxing law really helps nicks defence here. she has doxxed him (ie harasssed him). her showing up at his property now is trespass. her 'innocent" status is extinguished.
