@Cow cc @JeffSchaller Yes, it is possible for users without the view deleted posts privilege to retract flags on deleted posts. I've done so many times on various sites. However, it's not possible through the stock UI. It can be done through either calls to SE's internal endpoints or through the SE API. There are at least four userscripts which would allow you to do that. Two of the userscripts are not yet released (both my work: my development version of FIRE and Flag with Preview). One of the userscripts has been removed by its author. The fourth is Flag Retractor (
