you simply have to build the network in such a way that it is not worth it for anyone to cheat. The problem of post-steem chains is that content earns for a short time, which in a way forces authors to produce large amounts of content if they want to earn. The problem is that everyone has limits on what they can come up with and even the most talented author will burn out. This causes many people to lose enthusiasm for it, but since they have already built a large blog, they want to use it and therefore start to scheme and cheat here ;] The solution to this problem is to create systems that allow the best authors to earn indefinitely as long as their content arouses interest. This means that at least some users, instead of looking for a way to cheat, focus on the quality of the content. It also gives an excuse to pay for advertising, so it creates a source of income for the network.
I am yelling it for years
