In all likelihood, the judge's order related to data collection and reselling is not legally enforceable. They weren't parties to the expungement action, so the judge doesn't have jurisdiction over them. And, the First Amendment protects the right to say truthful things pretty absolutely.
Arguably, if the sites provided the information without making clear that it might not be current because records were expunged or corrected, there might be a claim for negligent misrepresentation, false light, or even defamation, but I seriously doubt that even those claims would hold up.
The language in the order might cause sites to comply out of not legally justified concern, or just a desire to be accurate, even if it is not enforceable. So, it doesn't hurt to bring that information to the attention of such sites and ask them to take down the information. But, when push comes to shove, I very much doubt that you would prevail in court enforcing that order against them.
Certainly, if you do nothing, they will do nothing, because they are not psychic and have no idea that the court order related to those records has been entered. Even a valid and enforceable order directed at a party over whom a court has jurisdiction is not effective until the person ordered to comply with it has notice of the order. And, there is no system that gives sites like that notice without you taking action to inform them of an order.
