We will only show you a Stack if there are enough people who match your preferences. You could consider expanding age, distance, or other preferences to see more people. Does this mean you're hiding New/ Popular people from me if I don't pay? Nope! If you want to focus your search or see them all at once, you can pay to see the Stack, but new and popular people will show up in other Stacks too.
