So I have been tracking some medium competition keyword niche's serps, there was a website ranked #1 with 0 backlinks. It got banned like a week ago, and today I saw that the owner bought a new domain 2 days ago which is ranked in page 1 today. He 301'd the domain that he had ranked before and then got banned?. Is he using SAPE along the 301 redirect? Or in the domain that he is 301ing?
