Mr null has no Identity, his anonymous nature made him almost non accountable for any loss encountered in cases of transactions with him.
I made a few SBD and needed a wider audience as a newbie. But due to previous experiences with few online promoter i decided not to subscribe to any bot promising to help promote my post. But luckily for me, I found the
Steemit promotion button

I sent a few SBD just to test how it works. And after 2days of no result, I checked my transaction history and noticed i just sent almost an entire post earning to an unknown Identity 
The logic behind this feature is beautiful. As explained by
The
which no one has control over. This
means that once money is transferred to
future hard fork we will remove the
Steem Dollars, Steem, and Steem Power held by this account from the supply, but until then it is effectively gone.
This means the money is distributed to all stakeholders. Since all payments are made in Steem Dollars and Steem
Dollars are similar to the debt of the
network, it means all payments made to
promote posts serve to reduce the debt
load on Steem which increases the value of Steem.
But a lot of Steemians unknowningly sends SBD on daily basis to this account and often times end up making awful remarks about the community. A more awareness campaign on this needs to be made.
I will suggest the feature be reviewed since the community debunks affiliation with it.
Steemit, Institution Disclaimer

Or the promotion services made more effective with the disclaimer when spelt out so Steemians don't feel scammed when they subscribe to it.
