I get annoyed by the number of links issue too, but I'm so hungry for submissions I've become more lenient on that issue than I was a couple months ago... that and MrYum's arguement about "ad space intent" as opposed to raw number of links.
But lucky for me I've only had to be a hardass about misleading "enter" sponsor links on the warning page a few times.
Personally, I don't mind "enter" sponsor links on pages other than the warning page, though I don't think I've ever used it on a freesite myself. Seems to me that once the experienced surfer has "entered" the site...
