As far as I understand (maybe I'm wrong, using G-Translate), the conclusion here is that if you vote more, you get less curation rewards?
If this is what this post is saying, then that is not true, because the curation rewards depend on the voting efficiency. You can get better voting eff with more post, or with less post. No correlation in it. Usually voting more means better curation rewards.
