People have gotten millions of airline rewards miles through credit card churning. They don't even try to conceal what they're doing. For a while, people were purchasing thousands of dollars in coinage from the government, using their credit cards.

These credit card offers are designed to exploit people who have difficulty living within their means. It's interesting how creative people are in exploiting the loopholes left behind.
