The fact that this page exists proves that Petzl sincerely cares about its customers. Petzl knows that many customers will use their gear in ways that Petzl considers unsafe (for example: using a grigri without holding onto the brake-side of the rope) but instead of simply saying "Don't do it" Petzl researches, tests, and creates wonderful diagrams to show its customers and all other climbers the dangers of self belaying and the safest way to do it. Thank you Petzl, you are now my all-time-favorite climbing company.
