Of late the discussion has been about 'trust rank' where websites are evaluated for external (web community) and internal (website developer) signals of authority and trust.
Anything that can be 'gamed' will always be a target of filters. Anything that looks like it can be gamed will be targeted by SEO, which in turn will beget further filtering efforts.
Take a long look at the following thread. It's a WebmasterWorld gem.

Curiously if I search from Google nz or Google au or other English Google it's as usual but if I search Google in the UK web or UK results we're gone for now....It's virtually,only .co.uk in the results.
I have a similar sounding domain with .co.uk extsn should I attach that one...will it help?
I know there is a similar thread on this topic elsewhere but this is a fresh problem.
