Sure. But as we have seen, accounts of that size that flag catch a lot of heat for it. Are you sure that a company like Samsung or Canon would want to flag users like that...for the explicit purpose of trying to censor them? What do you think that would do for their image? And do you think that other users would not aid in upvoting such posts? How about their competitors, who would love to take advantage of the situation?

There are always remedies for bad actors. You need to trust this system a little more.

maybe. overall I agree advertising is probably one of the experiments that must be done.
But I'd wish the revenue problem could be solved a bit more creatively than this.
Ads seem like such a huge step backwards.

As long as we're talking shares:
what about a crowdfunding branch that puts up STEEM funding, effectively buying shares in the startups.
When profitable, these shares should pay a dividend the shares themselves that go into a blind escrow account or something and the dividends must be converted to STEEM.

By taking real sales and converting them to illiquid steem, it would have the same effect of injecting capital, although through the markets and not the reward pool directly.
