Is there a bet available to determine if the weather forecasted was impacted by a hair dryer?
hilariously
"It sucks that someone potentially tricked a temperature sensor with a hairdryer to scam actual gamblers out of potential winnings" really missed a chance to say it blows.

It never occurred to me that Goodhart's law could be applied to betting, but here we are :)

I can't believe there's no honor among the gamblers!

Gambling addicts will really gamble on anything, won’t they? It’s a bit strange to see degenerate gambling dressed up as “predictions”.

I think what's also telling is Polymarket's non-reaction to this. If there are obvious concerns that the outcome was manipulated, I'd expect them to invalidate the bet - otherwise they're effectively incentivising manipulation.

Is that better or worse than invading Venezuela to rig a Polymarket bet ?

If that happened, has a crime been committed? I don't think so. Well, maybe tampering with the thermometer might be a crime, but, on the gambling angle, I would say it's not.

is this what the cryptobros are doing now?

Just to be clear, my understanding of news here is France is that there is an investigation for someone having possibly rigged the weather sensor but there was nothing release about how this could have been done. The hair dryer thing is a joke, even if it is still a possibility, but just to say, it could be a cover, it could be a hot air gun, it could be a hack, it could be just luck, ... Take care because there are ai generated videos of a guy with a hair dryer doing that, but these are fake!

They said that Cobra would never acquire the pieces of the Weather Dominator. Now we’re doomed!
