It's not even that he may be lying. It is that this is so obviously a disposable site run as a marketing gimmick by a marketer. This doesn't strike me as "Show HN" as much as "Market to HN." Almost every post is so thick with marketing buzzwords it's impossible to read them.
This whole thing seems more like a get-rich-quick scheme than a business. HN has never seemed like a place where get-rich-quick schemes are valued.
