Neutral feedback does not affect your rating.

Also, as a seller when you go to leave feedback to the buyer, I believe I remember seeing a "report" link of some sort in order to dispute the transaction.

I had one auction where I paid the invoice 20 mins after auction end, the seller took 4 weeks to ship (after a paypal dispute was filed). He got negative feedback for the transaction. What does he do? Leaves negative feedback ("Pay faster next time") on my account.
