What I propose is far beyond the capabilities of any industry or organization, ICAO is the only one that comes to mind. There needs to be a restriction put on the ability of airlines to offer ridiculously low ticket sales.
ICAO could not do this as ICAO does not make regulations. ICAO produces RECOMMENDATIONS which individual Governments then decide to adopt into their local laws - or ignore!
Also restricting what companies can charge for a service is illegal in most countries! It's called the free market.
