Actually, this will be not very bad - funny thing is, when new people will see that on platform, they will think, that this is a source of all rewards of other users.

And to be honest - I think a lot of users will be less suspicious about that Steemit, even if they will later learn, that Steem works in a different way, and funds from promotion just helps reduce supply of SBD.

That said, I hope we can come up with something slightly more novel than every x-th posts. :/

We do not need to have something perfect. We need to have something better. If this will not work, this can be removed or changed.
