Don’t know about US, but in EU you legally have to publish your address and it will be shown on the store page if your app has ads or in-app purchases.
Anyway, ads are just a sidechannel for purchase. There is a product advertised, someone buys it and developer gets the cut from the seller of the product. This is how ads work.
Just in case they're looking in the wrong place (looks like they moved where this information was since I last looked), you have to expand it in the sidebar on the right.
all it takes is one guy who gets too mad for some reason
and it's gonna be a lot more costly for you to do anything about it vs. that guy who gets to be completely anonymous about it
