Please share here if you know what you are talking about in regards to SEO and subdomain PR in gooogle. Recently I've been tracking a few sites that have decent PR with their subdomains that simply forward traffic to their sponsor upon click through from gooogle. It appears that gooogle crawls their page but the only way to actually see their page is to view the cache because of the instant forwarding. All that is fine and dandy but crazy thing is they are gaining traffic from searches for sites that don't belong to them. For example (note this is an EXAMPLE) lets pretend I search on gooogle for gfy.com ...I am seeing that pages with URL like the one below is very easy to rank highly and pull traffic within any niche.

Why is this allowed? Is it a loophole? Is it fucking stupid?
