Based on some dismissive reactions from people with large and small stakes to the notion of plagiarism and other abuse bringing the value of their own stake down, it's important to remind anyone reading this of the nature of the Steem network: all accounts are stakeholders. Dishonestly earning posting rewards is fraud against everyone here.
I think your concern about curation rewards is nonsense.
I may have been unclear. I have no concern about the curation rewards themselves. I do want to encourage professional (profit-oriented) voters to consider more carefully in the future what they push to the extreme upper end of reward distribution. Whether that will be successful or not, I can't say for sure, but that won't prevent me from trying.
I still don't see how curation or curation rewards has much to do with anything. Aside from some of the accounts that automatically vote for my posts, I don't think people were voting on this post in the interest of gaining curation rewards.
