What does this image mean? It was posted without explanation after months of silence.

So a podcast host (Mike David of Redbarradio/Scarsclub) has a life threatening illness and recently has been out of commission for almost three months, even though he does 8 hour shows twice a week normally.

He has said before if his illness kills him (which it will) he would just let the site go down and we'd have to figure it out.

He has a wife Jules Felker and a web developer Cameron Malek, who run his site and may have posted this image.

What does this code mean? Is it passwords to his site to let people trash it all on the way out? An encoded message? Bitcoin wallet?
