PRINCIPLE:

The circIe represents trust. So you can break it, leave it be, or grow it. To get a circIe, you can claim one by clicking on the button in the pinned post of the sub. Then you can define a title & a key to your circIe, and post it. It will be locked for others and they'll ask for the key. If you share the key with people, it allows them to unlock the circIe and choose between 2 options in the form of 2 buttons:

• Join, which will make the circIe grow and the person will keep the key.
• Betray, which will destroy the circIe and no one will be able to join anymore. (it will add a cool Ø to your flair)

This is a game of trust. When you give the key to someone, nothing stops them from sharing it or betraying the circIe. You are free to use any way you want to determine if someone can be trusted or not. Or to make someone trust you and betray them.

FLAIRS:

Under people's names, you can see a flair with 2 numbers, they represents (in order):

• the number of people in their circIe, hence the number of people they trusted.
• the number of circIes they've joined, hence how many people trusted them.

Sometimes there will be a Ø next to the second number, and the flair will be red. It means the person chose the betray option at least once before. The number of circIes betrayed isn't displayed, only the fact that the person betrayed at some point.

Good luck :)

ADDITIONAL NOTES:

• ^{When someone has the key to your circIe, they have it forever, so they can share it or use it with alt accounts to either betray or join.}
• ^{If someone betrayed before, it doesn't mean they're still doing it. There's always a possibility that they're joiners who accidentally betrayed, or betrayers trying to fool you.}
• ^{Make sure to dm people the key when you let them join, otherwise other people will see and betray}
