I do think bidbots are false advertising.
If I may interject something. I agree wholeheartedly with the above statement, especially if they're being used to push junk content in order to game the system.
Vote buying for a bona fide post, however, is NO DIFFERENT from ANY OTHER automated curation trail. (of which there are quite a few on the Steem)
The only difference is, as the vote buyer, I'm proposing to a bunch of people what to curate, i.e. my own post, and for a hefty price. That is considered selfish by some. As far as the ecosystem is concerned, a quality post is being upvoted, and the voters collect curation rewards from the pool. (There is even a small extra benefit of SBD being recirculated which is supposed to help with inflation, if I understand it right.)
On a curation trail, some content guru dude, or some group, gets to determine what is considered "quality" and a bunch of people follow this sight unseen with a similar profit motive, in the hopes the guru picks content that shells out the best curation rewards. This behavior, however, is considered "social."
Many a poor bastard noob fell for this, thinking the dough is now rolling in, and got bitterly disappointed instead when the socialist caravan moved on. Many of these folks left and have been badmouthing the Steem for this experience ever since.
So who is really doing harm to the ecosystem here?
With regards to your club example, as long as the club owner keeps it up, the paid actors and the club staff have employment and can EAT. If it works out, at least the club staff will KEEP EATING. So I can't see anything wrong with this kind of "raging capitalism," provided, we're talking about a bona fide night club that's here to stay. (as opposed to a scam to bilk potential investors)
