This isn't a viable strategy trick to get a high ranking, it's just an interesting case study with a difference.

We have a lot of theories and ideas, here are three points to summarize. 1. Not (entirely) related to 302 redirects. Initially we thought the root cause was 302 redirects. We all know that Google firmly believes that there is nothing wrong with the use of 302 redirects. We feel that the file hosting method is difficult to disentangle.
