I know reputation rating exists but I would like to know if we can see users rating for helpful flags (if so, for Pro Webmasters and All Time). I'm just curious.
That feature has been explicitly removed for most "normal" users. There's a helpful/declined flag metric that is visible to mods and to oneself, but otherwise that information is generally kept low-visibility to prevent prejudicial actions against a user and to limit improper incentives.
There used to be a "flag weight" value which is no longer made clear to users or moderators.
