The "me" in the article is not a person, but a corporation. The person suing is not the lawyer, but whoever engaged the law firm. And an entertainment venue is not somebody's house.
How about ... If you work for a company that is engaged by a company that is suing us in a business dispute, we will harass you by excluding you from an unguessable amount of venues and events. We're warning you of this but we won't give you a list of those venues and events, you'll just find out when you get excluded as you go about your private life. And we don't have to get a green light from a magistrate to do this, and we might continue doing it after the dispute is over if we don't like your attitude.
I think the scale allowed by automation is important in this case.
If the software is being used in criminal cases then, that's bad. If it's being used the same way a picture in the local 7/11 is used to say "don't sell to this person." then it's not so bad.
If it's being used to track someone as they walk around town, then I think it falls into privacy.
In this story. The lawyer was warned. It's reasonable to assume if you're suing me, I don't want you in my house.
