I am new to SEO and GSA, but I learned quite a bit off this forum (many thanks). I came across <EDITED: deleted, since examples have been provided> and they are ranking #1 for a few SEO-related keywords. I checked their backlinks and they are all CHINESE backlinks and are spamming it to death. 95% of their backlinks are just pure spam. (no tiers, no high PR, just spam) How they heck are they ranking #1 like that. Those backlinks seems to be even worse than blog-commenting. Most are dead etc. Any input on this will be appreciated.
