Since MB is not a bid bot

Sorry, didn't want to generalise MB to the rest!

In our case, we give a few percent profit, so more than 1usd comes out.

Yes, I know that, but it was +/- the same!

What we calculate is basically how much goes to the buyer? So with 50% curation, if you pay 1 SBD we need to vote you for 2 STU so you get 1 SBD back (simplified).

Same applies for the bot. The vote worth 2usd has 1usd curation reward and the buyer pays the other +/- 1usd!

Buyers need to be aware that the flag pool allows for new mechanics in the game :)

This is gona have an impact for sure (but isn't included in our reasoning above).
