An interesting system occurred to me. I don't know who could implement it. It is possible to develop an automatic algorithm that would work like a lottery. This algorithm could add up the number of SBDs burned by members of the "promoted" page during a certain period of time, for example, 24 hours.

After that, the author, whose post at that moment was the highest, would receive a reward - 50% of the burned SBD. The more participants, the bigger the prize. I'm sure such a rivalry would result in the voluntary burning of significant amounts of SBD. Even bot lovers could participate in the competition.

Funding of rewards must be done with Steem.DAO. That is, someone needs to write a proposal. I am sure that it could be supported, because in this case, in essence, the blockchain "buys" itself a reduction in inflation. In the end, everyone wins.

The system has one weak point. In the blockchain, everyone can find out who sent how much SBD to @null. Then the last member can just send a little more SBD to @null. But this can be overcome by the fact that the period of time during which the winner will be determined should automatically change in a random order every time.
