Given theres no “meta data” on a unban event (reason for example since unbans/untimeout doesn’t take reason) then you won’t know this the old way either. (and the old way using /events wasn’t super reliable, the number of times /evnets would have no events as the cache had been reset was gnarly)
From the raw data on the old or new system you don’t know if these events are “important”
Unless the moderator marks it as such in your system.
Was it a misclick, was it an unban from an appearl? You don’t know from the raw data alone as I’m not sure what conclusions you were making from the old /events/ endpoint
