[Useless]

Even the most puritanical reviewer will accept a hardcore PenisBot recip because they know it's a strong traffic source. It's just good business.

To answer the first question, this:

Hardcore banner, image, counter or link to another porn site on your index page.

does not appear to imply that all of those things are wrong. Notice the word 'or'. Sounds like they have a bunch of options all lumped together and that's the one they selected without indicating which one is the precise reason for rejection. You know whether or not you're using a hardcore banner. You know if you'r eusing a counter. If it's not one of those two reasons, then you are linking to another list or promoting a sponsor that they have banned.

That's my guess.

And now my aside. People who don't allow hardcore on the index page need to lay off the crack pipe. Child-friendly warning pages would only make sense if Google only indexed index pages. Don't submit to them.
