Betting platforms specifically work to identify customers who act in such ways and ban them from the platform. Developing accurate odds costs money, it's cheaper to just identify "advantage bettors" and ban them.

I'm not sure this applies to these prediction markets. Normally when gambling you're at a casino playing e.g. blackjack, where if you're winning more often than expected you're taking the house's money.

But this is more like playing poker, where overall the casino could care less if you're continuously crushing the other players, as long as people keep turning up to play and they keep getting a rake.
