Hmm, this is the best guess here IMO. This person did say it started occuring within the last year though. I just created a site a month ago with 2000+ pages and I did notice only 5 were indexed, which was quite annoying. I just suspected it was because I didn't have enough backlinks yet so it didn't want to waste time on it... interesting it may be what this original article is about. But yes, I 100% bet its because all new sites now have an enormous barrier with the sheer amount of fake content that can be generated.
