Where to get High-Google-Trusted BackLinks

Really guys, I am pretty hecked! :date:
Yesterday I was drinking a beer with my competitor and he showed me the URLs from nationalgeographics.com, ucla.edu etc. he BOUGHT recently. I though that such trusted sites do not sell non-relevant links but all these backlinks contained links to his black-niche site. He told me that each of the link costs around $500 but who cares if it is a nationalgeographics backlink?!

Please share your ideas how did he got those links? I want them too.
Could they be hacked? Maybe he bought somewhere at the closed high-quality link-stock?

Any help?

maybe he knows an editor of the page and made the deal

lol you can get high google trusted backLinks in services for sale section in BHW
