There is so many usernames here that is highly desired like anime names that is binded to accounts that hasnt been used for 1-2 years there should be some kind of username cleanup for those really long time inactive accounts
Once in a while, peppy deletes accounts that haven't been active for years. Plus, you can change you name to one that has already been taken if that person hasn't been active for 1.5 years, and has less that 400 plays. However, you need osu!supporter for that.
Yes, you can take the names if they have less then 400 play count AND inactive for more then 1.5 year They won't change to anything near inactive as that
