The top contenders I have experience with is: -Aesprite. It's paid. It's good. Built solely for pixel art.
Free stuff: -LibreSprite- this is the open version of aesprite before it went paid. I don't know it It's still maintained or updated, but it may suit your needs.
-pixelorama- web based made in the godot engine.
Not sure about all the personal stuff, but it is against the TOS to transfer the account.
Big answer is I DONT KNOW, but...
For payment/address stuff you could change them then try to revert to see if it works. For payment get a $5 gift card from Wal-Mart and set that as the credit card.
