You're right. Here in Steemit there are many people who call themselves liberals and anarchists, but at the time of any problem they ask for more regulations.
The owner of the restaurant may not have any direct incentive, but if he does not clean his restaurant nobody will go to that pigsty, in the same way, if we don't clean Steemit, well, it will be boring to browse in a lot of content that we consider trash.
But it is important to clarify that no one, absolutely no one, no whale, should take responsibility for saying which content is of quality and which is not, because that would be an emulation to the regulations of the platform, the main objective of this voluntarist system, is that each of the people can vote and place a flag to what they, personally, consider wrong. The whales must be the first, although not the bosses, to give the flags because the minnows will never have the ability to face a revenge, in addition, the minnows are the ones that have less interest in the progress of Steemit since they are the ones that have less money involved in it.
There are some things that are still off limits. For example, I watch for and point out child predators when they are found. People who are stealing other people's content should also be called out for it, and we should prevent them from profiting from someone else's productivity.
I am sure that there is relatively enough content to put the flag, the goal is to be done individually but by a large number of individuals, because if not, it really does not make sense.
