Free Rice

This issue needs to be addressed. Presidential candidates should be taking a stance on this. Concerned citizens should be decrying it. The problem is freerice.com. By testing your vocabulary prowess, you can donate rice to feed the often-mentioned hungry people. It's an interesting idea. And if you're an idiot, you might also think that it's a productive way to spend your time.
