> Spamming account creation won't work, because accounts need to have been created in April or earlier.
Pre-creating "sleeper" accounts is a common way of circumventing this, though it does require a degree of long term thinking/planning.
There's probably more to it than that, and Valve just isn't telling us all the details.
It's likely they are weighting accounts that have a lot of (recent) game activity and game purchases as well. Plus, they have access to hardware information via their hardware survey, etc.
Oh yeah I remember reading that in a book about botnets. Valve can only do harm reduction here, but calculating actors will seep through.
Then s/g still applies

It's not just an account with an age, they have to have made a purchase. And shipping address + payment info also help eliminate duplicates.
