I still think upvoting the return proposal is not the same as downvoting an existing proposal. Both are two different things. The return proposal is unnecessarily creating a huge bench mark for the proposals to even get listed. A small guy who is just starting with an idea will not even be able to come to the benchmark.
With the current system, we don't even have an option to bring a proposal down. If something is overrated, the community should have a facility to reduce the rating of a proposal. I'm sure return proposal is not a solution. It is just preventing to some extent but unnecessarily creating a huge benchmark like I said.
This system needs to be fixed and I think downvote would be an ideal solution.
For a moment forget the small guy who is just starting, and imagine the rich guy who is exploiting. He upvotes his exploit and downvotes everyone else thereby doubling his power. The small guy is even more screwed than when he had to face a return proposal, particularly when more than one rich guy is pulling the same shenanigans.
A return proposal is not an ideal solution to the small guy's predicament, but it is a solution to keep things moving without doubling the risk of centralization.
We already have a fair amount of centralization here already. We cannot help much. And yes return proposal helps but it definitely is not a solution.
