Okay, 100% of author rewards for this post will be burned.
I have refrained from voting for proof of brain posts. POB burned is POB that doesn't go as rewards to users. But I wanted to point out you don't need to collect money, and then burn it you can set it to burn by setting null as the sole beneficiary.
In advanced settings click on "add beneficiary". Type 100 so that null gets all the rewards. Then type in "null". So now all rewards will go to @null directly.
What do you think?
