Apparently Steam used to have a policy of shutting down the accounts of people who did too many chargebacks, locking them out of whatever else they'd bought before.

If you have to do a chargeback you should never give that company access to your credit card again.

Yes indeed, so, companies that you can't trust, but can't afford to piss off, should be the definition of anti-trust targets.

In an ideal world.
