How do I leave similar worlds ?

You can check in any time you like, but you must never leave.

Go to "Account Settigs, Leave Similar Worlds", type your password, click on "continue," click "continue" again, choose the reason why you are leaving and the period ( just for a few days or forever). When you want to go away forever click "cancel" - otherwise "log out"

Just don't log in any more.

Quietly and carefully

You could put your account on vacation mood in settings.

The similar worlds will not let me close my account

Just click your heels together... Oh, no. Wait... 😄
