(Original Report: After blocking some user by accident or to check how it does affect your frame-rate and then unblocking that user - it will only be unblocked for a while, after rejoining that user will be still blocked. And this state never changes, so it is just impossible to unblock someone from game https://vrchat.canny.io/bug-reports/p/unblocking-does-not-really-work )

This was marked as complete despite the issue still being a problem. a user who reloads the instance after unblocking me will still have me blocked.
