The science of history is a great bulwark against the stream of Time; in a way it checks this irresistible flood, it holds in a tight grasp whatever it can seize floating on the surface and will not allow it to slip away into the depths of oblivion

I deleted two microbadges I didn't want, and some bot sent the same two badges to me as a "reward" a day or two later. I would think deleted would stay deleted.
My guess is the system compares a list of people who meet a criteria for award to a list of people who own that particular award badge and sends them out based on that. Keeping another table of previously awarded recipients for each badge is probably just more work than they want to do for system awarded badges.
