Back clicking would be a disastrous signal for many. We deal in contracts that always require three to five bids. Our users are always going to click back and check and others.
Eliminating non content links as carrying any value would help with paid links. Non directory, non content links have little real value most of the time.
I agree with your other points.
I'd add they should penalize those gaming the system with duplicate sites. Give them a few day blacklist and they'll get the message. I'm tired of all the brandkeyword.com domains that are part of parent sites ranking. It's spam.
