One may argue that there is some misunderstanding but at least immediately blocking the app in the country it undoubtedly misbehaves would be a very logical first step before digging deeper.

Why would Apple not do exactly that?

I am curious what Apple's vector for checking this would be. Look through an app and any of its links and check against a spam database? Add extra cautions when users click links that link them outside the app (lots of sites do this on the web when leaving their forums etc.)

In this case, it is quite obviously a scam based on the marketing and advertising that has been added as context to the app, but the app alone and probably most of it's app code looks like a running game. (Not absolving Apple, just curious on what they might do here that scales)

From a kids game to a casino app, this is unreal. The good news is that someone took notice of this exploit.

I hope that Apple will consider this scenario as many kids are using gadgets as means of entertainment.

Wouldn't you be really happy that Apple is not paying too much attention to apps and that you are able to sneak "illegal" content into an app?

In app purchases (in case you were wondering) and obviously being a hidden casino it wouldn't.
