Topic: Need help removing accounts with share play enabled

Good day all.
I am here hoping to see if anyone could help me out.
So myself and my son share the ps5 till I get him his own and he likes to make new accounts when he rages at an online game and starts from scratch so it doesn't look like he's played bad ,now he deletes the accounts makes new ones and doesn't disable the share play .now I know you can only have so many accounts with shareplay enabled before u get all this errors etc. I have asked him for the emails I'd the other accounts so I can de activate them but he can't remember he says. Is there anything I can do about this ?
