The previous owner of the username "oof" recently changed to "chuwu" on November 1st. Yesterday on November 25th, a different account claimed the username. This was before even the original holder of the username would have been able to switch back. It is interesting to note that also the new owner of the username "oof" (UUID: ec67b5f8-fe23-4fba-ba44-2431624a7b13) seems to have claimed two usernames in the same day according to both NameMC and MCUUID. The other username claimed was "dsofijdjjg".
