问HN：你们是如何防止儿童访问你们的产品的？
在推出我的前几个应用后，我遇到了一个意想不到的问题：年轻儿童是最有可能点击我广告的群体，他们使用的是父母的手机或平板。这绕过了年龄限制，实际上还产生了累积效应：他们太小，无法拥有自己的设备（所以他们只是安装了应用却从未使用过），浪费了广告预算，最重要的是，导致目标用户群体偏向于像他们这样的用户——因此广告投放最终会更多地针对他们，因为他们最有可能点击广告！
这导致我的所有广告活动立即失败，无论我如何调整年龄限制（毕竟是父母的设备）。我已经更改了设置，停止在游戏和平板上展示广告，这稍微有所帮助，但并没有完全解决问题。
显然，我不可能在应用中添加真正的年龄验证功能。

After launching my first few apps, I'm running into an unexpected problem: younger children are the ones most likely to click my ads, using their parents' phones/tablets. This gets around the age restriction, and in fact, has a compounding effect: they are too young to have their OWN devices (so they just install and never use again), burn ad money, and most importantly, skew the target demographic towards users like them- so ad placements end up targeting more of them, because they're most likely to click!<p>This causes all my campaigns to immediately fail, no matter how much I play with the age restriction (again, parent's device). I've changed settings to stop showing in games and on tablets, which has helped a bit, but not fully.<p>Obviously, there is no chance I'm adding real age verification to the app itself.
