Promoting content and purchasing influence is different than buying governance votes in DPOS (Delegated Proof of Stake). I plan to do another post on vote bots at some point. I think promotion makes sense, but I think the way it's being done now, prior to Hivemind ("Communities") is quite broken. I'd prefer actual promotion much like Facebook and Twitter do (inline posts users opt in to and maybe even get paid a little to see) over false popularity.
