Just my thoughts

That's the joy of the blockchain. It's forever.
You don't really have "an account", you just have the keys to permanently write to the steem blockchain under the name ag-randall.
If you want to make sure nothing else is ever written under that name/address, change the password without recording it anywhere.

Sorry it didn't work out for you, good luck in your future endeavors

better yet, sell someone your account.

Sorry to see you go brother, but I support your decision!! I will continue to show off your works that I have on both platforms brother. Be safe and much gold and silver to you!!
