Why Google still display search result so bad?

[taradmkt]

When I search this keyword Backlink คือ by Google browser(Google.co.th) then I saw these Domain that is spam keyword and worse content (Spin content and can not understand what it said)

อํานาจเจริญ.dmc.tv/?p=19
ฉะเชิงเทรา.dmc.tv/?p=28

พังงา.dmc.tv/?tag=backlink

หนองคาย.dmc.tv/?p=97

ขอนแก่น.dmc.tv/?tag=backlink

ชัยนาท.dmc.tv/?p=70

ตราด.dmc.tv/?tag=backlink

etc

As you can see the search result**.**

My question is

1. How to tell Google to check these network

2. Why these network display Top 10 for 3 weeks!!!!! and after that they rank drop.

3. Why Facebook page rank on Google in the search result

Please make me clear.

It has been said by a few recently that google has been rubbishing the search results to drive searchers more twoard the paid results. Not sure if this is true or not, but it'd be a huge shame and googles downfall if it were true.
