What I will do is create a compatible wallet on one of the exchanges and use it for any transactions I might try. My migration wallet will only be used to transfer limited amounts to exchange wallets or other Pi Network wallets if it's possible.
Transferring coins from my migration wallet to my usage/exchange / alternative wallets will be the only place I ever use my migration wallet passphrase.
Handle the scammer situation however you see fit, but you've got to handle that situation....
