“What good is that going to do the plaintiff?”
You can call yourself anything, but the ISP has your address, 186.111.222.123. How many times have you gone to a website in Timbucktu and seen advertisements from your local Sears? That’s because the ISP knows exactly where 186.111.222.123 is, right down to your street address.
Your IP address doesn’t track back to your street address. It shows your ISPs address or local hub. Someone can get your info from the ISP with an IP address, but they would need a subpoena to do that.
What’s to say you’re not typing away at some cafe with wifi?
I don’t see how you can stop a person from expressing an anonymous criticism of a union thug. In fact, I encourage it.
