I want to acknowledge the points you make here @coteclaude. It’s evident to me now that increasing the spam proposal cost to 10 ICP is not an effective spam deterrent. Furthermore, any additional increase would only serve to further harm the average stakeholder. I clearly made bad assumptions about what people would be willing to do to increase their rewards.
Speaking to others, it was pointed out that one benefit of the increased proposal rejection cost is that these spam proposals will result in 600+ ICP being burned over the next 30 days. It would be nice to know how the community feels about keeping the 10 ICP rejection cost if it results in more ICP being burned while spam proposals are still being submitted.
