I wish that more curators would look around a bit when casting their votes. Sure most users have deserved them and should make the most out of the insane price of SBD right now, but you don't have to be a genius to realize that someone who's constantly powering down and posting 10x a day while selling all SBD is doing nothing but siphon rewards from the platform. Now if you think of these examples, wouldn't you want some of those users to get flagged so that the rest of the platform receives more rewards?
I want to touch this point, but you seem to have gone too far in a certain direction, that only "giving steem back to the platform" is giving to the platform's growth.
If you make good content, you're also creating value for the system, and more reason for users to spend time on it and engage with others here, and also examples of what good content looks like for them to make.
And then they use the rewards they earned outside the system, and that's fine.
Expecting users to give to the system twice, both in giving it all of their content and not getting payment out of it is, in my opinion, misguided. You can laud those who do that as their values align more closely with your own, but actively casting shade on those who don't is not the right direction.
Now, if you neither create content nor help the economy, that may be another issue, but in the above quote you're specifically talking about people whose content is worthy of curators' love.
