Why isn't anyone joining my Club?

Inactive Club:

If a club remains inactive for a week—meaning no chat messages, no updates to club info, no members joining or leaving, and no tasks completed—it will not be included in the current tournament and will be set to inactive.

To keep your club active, make sure to write and send a message to the chat section every day.

High Requirements:

If you set your club's level requirement too high, like 200+, it will only be suggested to players at those levels. Keep in mind that there are fewer high-level players, so your club will be shown to a smaller pool of users.
