I think you hit the nail on the head thought when you mention massive
user base. Probably at the outset of a spam campaign a bunch of users
get the spam, flag it as spam and then google just marks the rest as
spam for the several other million users :)

That said, gmail isn't perfect either which indicates a measure of the
difficulty of this problem.
