It's all well and good to flag wallets with perfect win rates as potential insider risks, but that alone isn't a trigger for action; it just creates a lot of noise. Someone consistently winning on Polymarket might just be very good at their research or specialized in a niche, like the neighbour who always knows which stocks will drop based on supply chain news. We need more than just high win rates to stop the wrong people and avoid invalidating genuine expertise; otherwise, we'll just be chasing shadows.
