I think the post to which you're replying was the only ever instance I had bought votes in an effort to inform people of the upcoming economic changes as part of HF21. It was also under an utterly broken system, and subject to downvotes consensus (which admittedly were strongly disincentivized at the time.
By definition everyone has upvotes and downvotes in accordance to their stake, which is finite and the aggregate of all these votes is the consensus
I don't have a stance against promotion or advertisement. I do have a stance against selling votes as an alternative and far more profitable means for stakeholders than honest curation. If honest voting only paid half as much as vote selling, over time very few will bother to vote honestly and this will completely undermine our Proof of brain content discovery/rewards system. This is likely why your bought buying posts got hit by mine.
