Sold Wii and forgot to delete users - what can I do after the fact?

Before y'all get hyped up on how stupid that was - I already know I'm a dumbass.

I sold my wii RV1-001 and forgot to delete the accounts and users. I never bought games on the console so I don't think it has my CC on it.

I already changed the password on Netflix account.

What else should I do to try and protect myself after the fact?

Thanks.

nintendo estore

I don't think I ever set one up - do I go to Nintendo.com to check?

Thanks.

No account so I think I am good. Thank you guys!!
