>GMail doesn't actually filter spam. It just hides it
This is not accurate. There is a long on-going issue with GMail (and others) wholesale blocking delivery of email from domains/IPs/providers it deems to be spam or otherwise inappropriate. GMail users get no indication/notification, and generally have no idea that email sent to them was simply not delivered.
