They really are pooping where they shouldn’t... and creating more garbage than they’re allowed. It’s certainly not a “no trace” event, despite what’s advertised.
"Leave no Trace" is an impossible goal, but by saying it you help ensure that there is hardly any garbage.
We camp on something like 100 ft X 400 ft and spend the last hours with a crew of people going through the entire site inch by inch picking up ANYTHING. A toothpick is too much. A cigarette filter is too much. A sequin is too much. All camping areas (really at all events) are reviewed this way. Then after everyone is gone, they sweep the areas again with the official crew and note anything they find. A few months later it gets posted on a huge map online with red/yellow/green markings. If they found a beer can on the south west corner of your camp, there would be a red mark there. Then next year, camps with red have to explain themselves, and find it difficult to be allowed back.
Compare this to something like a music festival.
There's nothing new in the Vice article. The areas noted in the article are common areas far away from the site. People are pigs, sure, but what is the degree of the problem ? No mention, and just another dump-on by the media who can't convey the event properly.
