I don't know what the thing he's doing is supposed to be called, I just know it's not what the headline implies. The only thing oniony about this article is how badly the author fucked up the title.
If it weren't for the clickbait of "What lol the AG wants Dollar General stores to avoid him" then this would never get views.

"Restraining order" is one of the most deceptive ways this headline could have been phrased. Yes, technically he is requesting an order that will pose a restraint to the company. But Restraining Orders are also a thing. Being that misleading is journalistic malpractice.
