Allow siteowners to log into G Webmaster Tools > list all backlinks > check a box next to each link that should be discounted > confirm
That would make it clear to G that the siteowner did not request and does not want those links, and thus, no need for any penalty whatsoever
Sounds good, but that may aid in reverse engineering the algo.
Suppose you bought too many cheap links recently and suffer a penalty. Very bad now, but under your scenario, maybe not.
Simply login to webmastertools and check the box to discount the suspect links. Penalty goes away, and you have another clue on what links they will tolerate for your site.
