While I don't see a disqualifying hurdle in principle for Steemit Business Accounts (SBA) these are my caveats: (1) overtly commercial posts are soul destroying (that's why BAT crypto has skyrocketed); (2) if the personal post/commercial post equilibrium is skewed no one will want to read much n Steemit.
What is the right balance ? 75% personal to 25% commercial. Who makes the decisions and who determines what is a commercial business post?t
If Steemit is going to add Business Posts then what about non profits too?
Another possible problem is the rise of spam affiliate links by SBA accounts. These links would take readers off Steemit pages raising the probability of the FB squeeze to keep readers on the platform.
Another concern is SBAs buying into Whale Steemit Status. Could there be a business tax system set up that redistributed Steem to personal posters?
Sorry, I don't understand the Steemit monetization system so I can't be more specific.
