Guys, stop trying to pressure the solver into doing anything. If you're nice, maybe he will stay and you can learn something from him.
We are all grateful for WP's post, sharing a method to securely withdraw a puzzle prize. Nobody is obligated to tip anyone just because you used MARA. You can always show your appreciation for what you've learned by directly sending a tip yourself.
It is not about a donation; that is up to each person if they feel like donating or not. It is more about valuing the contributions and not undermining them.

So, unless it is something else, the answer is simple: he has nothing to teach us that we do not already know. From what he says, random method with thousands of GPUs are things we already know. I suppose the most he could have added to the software is a database that records already scanned sectors to skip them later.
