Alternative accounts

I have the following alternative accounts. (Accounts marked with an asterisk '*' were created when I was not logged in.)

After December 7, 2023, any new alternative accounts I create will be made only from my main account (User:Yukio0819) on jawp. If any accounts created through other means claim to be my alternative accounts, please consider them impersonations.
