The default text for this notification states: “Account temporarily on hold,” and “you won’t be able to reply or create topics until a staff member reviews your most recent posts”
This seems correct if an account is automatically silenced by the system, but I was surprised to see this is sent when an account is manually silenced by administrator. That can be customized of course but may be good for the default system text to have a basic notification of just “Account has been silenced” if that is done manually.
Noticed this also, that isn’t clear in the form that what is written will be sent to user account.
