I feel like this is a "baby in the river" scenario. You know — after the third or fourth one, you should stop just diving in to save them and go look upstream to figure out who is throwing all the babies in!
We need to stop saying "wow, another person abused their position and inside knowledge to make money on polymarket."
Of course they did. Polymarket is practically purpose-engineered to be abused by people with inside knowledge. It would be more shocking to discover that no one was abusing it. It's basically a casino that lets you bring your own cards from home. I honestly don't understand why it wasn't shut down a long time ago.
