Basically you create 3 new sites supporting the money site, post articles daily for 7 days and on the last day you include a article with the money link. Then you send PBNs to it. In meanwhile you are sharing on social bookmarks and getting social signals. I do same thing with web 2.0's but no in so much detail. In theory it sounds good - a quickly built viral authority site linking to you - but the article is from 2014 so just wondering what are your thoughts? I am testing it out soon but will too like to know if anyone has tried it or what you think about it.
