If things weren't enough when it comes to kids spending their parents' credit cards on microtransaction stuff on mobile games, what about the ones for Facebook games? The case of gaming-whale has been endless or whatnot and the microtransaction feature is what makes gaming nowadays quite dangerous like you can buy the same few hundreds of the virtual premium currency countless times in which each few hundreds may cost $20 for instance. It's unlike a DLC item which once bought, it is available for download on any device.
This is basically termed "Friendly Fraud", in which a kid keeps on spending off the credit cards from parents/siblings/uncles/aunts/friends. I don't know if this is the same case for one of the addicted gaming parents or something but this is like gambling addiction in which an addict takes people's money and use it to gamble even more although the term, Friendly Fraud, doesn't definitely apply to that addict.
Maybe there should be a solution to the parents once the complaint is filed against one of their children spending too much off their credit cards whether it's a mobile game, PC game, console game or even an online game that is played on social media or any other web.
