I can't say that I disagree, but in that context, it's hard to find a way to "prevent" it. It's not the issue of people who are creating that content, but more about the people who are upvoting. As in most cases, those are automatic upvotes, preaching manual curation is the only way to do things more "fair." Not only that, manual curation is doing a lot more in decentralizing the reward pool distribution.

Supporting automatic upvotes, following big curation trails, or delegating all your HivePower to big accounts is shooting ourselves in the foot...
