Yeah that is the point, I think everything should be burned. I see the curation rewards as an underhand self-vote and a form of abuse (just my opinion). Not to mention, these burn posts could quite easily fall into the "spam" category.
I wrote a post about these a few weeks ago: Burning the Evidence
Good and valid point. Give me till day 7 of these posts and I'll change it over to a 100% burn to null and make note of it on the post.
