Thanks for your 'disavow links' comment.
It seems like such a simple thing, webmasters pointing out the sites linking to them where the webmaster wants nothing to do with the referring site.
I don't see how it could be gamed, but it might impact sites that currently enjoy reasonable SERPs.
Your reference made me laugh, which is good enough.
