answer to this comment, because of nesting level limit:

Again, self-interested curators simply cannot succeed in the long run by placing bot votes on crap accounts.

The problem is.. that in fact, self-interest curators cannot lose. Right now the only why to lose is not vote at all, so it is better to setup bot which will vote for crap.

And because right now with services like steemvoter this is so easy to setup a bot, right now a lot of people are just voting for anything what was lately popular.

Many of those people do not care about quality.

Steemit is an open-source, free market platform. You may want to regulate what people can and/or cannot do with their private resources, but that is not how a free market works.

Did I said anything about regulating what other people can do? No! They can vote as they like. What I suggested is change of rules (which would have to be accepted by majority of witnesses). I just have an assumption, that people basically vote for good content even if they are not paid for that. Why is that? Because good content very often is a reward, because its perceive value can be much greater than few cents from voting reward.

But if voting rewards will be removed, a lot of people which are voting only because of the rewards, will stop vote for stuff which in their opinion is profitable, but do not have to have anything in common with good quality.

Basically, I am not a Make Up expert, so if I would see a makeup tutorial I would no vote for it, because I do not have a knowledge to judge, whether all things are correctly explain in such tutorial.

But if I would be paid for voting for something what looks like it has great value, then I would vote for that stuff, even without checking whether this value is actually there.

If you will remove incentives, then mostly people with passion and experts in particular areas will first vote for particular content, because this is what people with passion do. They are reading everything about topic of their interest and they can very easily judge the quality of particular topic, because they see tons of other similar materials.

No value? Did you notice the dialogue the post generated in the comments? It cannot be said that the commentors do not hold it to have subjective value.

Most of votes were already there before any comment appear. Comment are there because that became "popular" because of autoupvotes. It is like fulfilling prophecy.
