Yes, from what I understand their entire business model is based on selling "world record" certifications to people and brands for pr/marketing stunts:
Guinness World Records is a brand of the Jim Pattison Group, a conglomerate that also owns Ripley Entertainment. It hasn't been connected with Guinness beer, the brand of the drinks company Diageo, since the early 2000s.
This is the most disappointing thing I've read all day :(
