The work around I've just setup & will see how it goes is to create a different Pandora account for my kids use with their Echo Dot. The idea is to allow Alexa to still use Pandora & bar it from the account I care about from getting nuisance stations created & from muddling up my stations list. (I did this all on my mobile.) This involves disconnecting the Pandora link (I did this in my Alexa app). I then had to log out of Pandora & back in with my new account. Then, back in the Alexa app, relink Pandora. This should link it to the new account. Then you'll want to go back & log out again & relog in with your preferred account. Hopefully, the mess is then contained in the new account that you'll never look at anyways.
