It’s because presale isn’t actually against their policy. What is against their policy is someone putting an inventory up that they haven’t confirmed they are going to have.

So like if they have the email from Valve saying “this is the timeframe you get this” and that timeframe is more less than than 40 days out, as long as they can confirm shipment within 40 days of the item listing it’s allowed.

I wonder if you get a new report option if the page has been active for more than 40 days, or if said issue requires a buyer to report them when they don’t ship within 40

Being said, I think valve should crack down on the resale of their product on platforms like ebay, if they can find a listing that links to a steam account terminate future sales. With how overarching their system is they could likely cite Policy violation and close the entire account as well.

I assume it would be fairly easy to look for identical card numbers across the platform, or require the primary account on the device to be the account that purchased it for at least X amount of days having the system like how phone carriers do with carrier locking.
