Nothing in life is "guaranteed". However, we often manage to form reasonable expectations about how things work. And when such reasonable expectations are broken, there are ramifications.

Imagine if large numbers of organizations started using Tinder to spread a message or support their cause. It would make finding a date on the app significantly more frustrating.
