Yesterday, internet users noticed that General Motors was handing out Reward Points for doing basic tasks. The company had done this before, usually for buying a car or visiting a service center. However, this time, people were able to get reward points from things like answering surveys and watching videos.

With these reward points, users were able to get discounts on GM merchandise, or even contribute to their car loan through GM Financial.

While the actual amount of award points given for these tasks was small, users quickly realized that GM had made a crucial error. According to Resell Calendar, users realized that they could create an account, accumulate around 15,000 points (worth about $150 USD), then transfer that money to another account.

As one could perform many of these tasks easily, it didn’t take long for people to accumulate thousands or tens of thousands of points. These points would then be sent to their main accounts, where they could spend them as easily as money.

For the most part, people just used this free money to buy accessories. However, some worked hard to chain together reward point accumulation sessions, resulting in them accruing millions of points and (allegedly) paying off their vehicles entirely.

Now, the point redemption site appears to be down, and people who have accumulated these points say they’re having difficulty actually using them. There’s no telling if GM will try to walk back these payments (they’ll likely try), but if anyone actually got away with paying off their car this way, we salute you.
