Wow, that's quite a fortune they'd be raking in if people are actually paying $100,000 per day for promotion.
I agree with most people that paid app promotions are almost universally bad, but the selective enforcement of trivial guidelines by Apple is still disturbing.
There's no better way to enact complete control over a population than to make sure they're all in violation of at least one of your obscure rules at any given time. Then you can ruin any of them just for looking at you funny, all while hiding behind the guise of "regulations".
The sad part is it's worth it. The app gratis users are crap, but charting gets you lots of highly qualified users, and if your app is decent you will make that money back. This is no different than botting was last year, except the people are presumably real.
For what it’s worth, in a previous HN thread, several users reported having received offers from AppGratis:
“We were told $3 per install or $100k flat rate for 1 day.”[1]
“I was also quoted a flat fee of $100k”[2]
