This NEEDS to be regulated. If thousands of companies make a living in your marketplace, you simply can't be allowed to take destructive unilateral action against their business without due process.
One guy reviewing tickets in a random location worldwide, working for minimum wage, takes a 30 second look at your case and closes down your account. Your company loses millions and goes out of business before any dispute even gets processed (If they even have a dispute system)
This is simply an insane way of doing business.
