Yes. I am the Steem Pope.

But seriously, just because something isn't explicitly forbidden, that doesn't mean it's OK. One of the stated purposes of the downvote is disagreement on post rewards, and many of us strongly disagree with vote-buying to inflate rewards.

Why should you buy your way to a disproportionate share of the reward pool, especially on posts that exhibit low-effort copy/paste nonsense, or nonsensical tirades?
