sort of an on and off situation chodadog. i believe that google doesn't allow fpas like you described. or at least, they don't like them. but would they remove them from a listing? who knows?
from:

"Do create a site with content and design that are straightforward, appropriate and relevant for visitors to your site."
"Don't participate in link exchanges for the sole purpose of increasing your ranking in search engines, or use programs that generate lots of generic doorway pages".
so if there are interlinked splash pages (to increase link popularity and the chances of being spidered) without content then it may be a problem...
"Reasons you've not been listed: you employ doorway pages. Google does not encourage the use of doorway pages. We want to point users to content pages, not to doorways or splash screens."
