How do accountability groups work?

Can someone give me a basic overview of how these groups work. There seems to be a lot of copying and pasting and adding people but I’m not sure what to do as a person joining.

Any help would be appreciated thanks.

it’s basically just a topic where you can compare your streak with other fellows.
you add your name and your current streak. to update your streak you have to copy the whole list and update your streak.

reason is that a competition where everyone sees your streak makes it less apealing to relapse

(this whole copy pasting thing will be changed. admin is working on an implementation for the app)
