Whatever Google is doing to fight web search spam does not seem too effective.
Here are search results for "ex-03 usb phone" query:
It gets worse: in my personalized (that is when I'm logged in) search results another two similar domains appear in first page thus giving more spam than real content. For comparison: none of these domains appear in top bing, yahoo or yandex search results.
Google search has spam reporting (https://www.google.com/webmasters/tools/spamreportform?hl=en) although my reports here are either ignored or sitting in queue for quite a long time (almost two weeks at the moment).
