people give tech courses on guns
why the same isnt done in a way for air bottle i dont know.
yeah point made, but not everyone goes to the tech courses, paintball companies (and indeed nearly every company) rely on people reading their manuals for safety guidelines.
Also, alot of paintball transactions occur over the internet. getting shopkeepers to tell their customers about it doesnt help these people. even if you put warnings up on the site (as i know alot of people do) people dont tend to read them.
In summary, people are stupid. if there is any possible way that people can avoid being told not to lube the fill nipple/rig they will. The only way i can see this being sorted is if companies like HPAC speak to everyone before an event and tell them.
