A Blocked History

I recently had a problem where i accidentally unblocked a user through a misclick, and i had left the one server we had in common i have absolutely no idea what there User was. Now they can message me whenever which really stresses me out TBH. It would definitely be helpful it there was a way to see when you blocked a user why they were blocked and if they have been unblocked. Yes i have opened a ticket with discord support sadly there was nothing they could do.
