Generally squatters aren't pigs because they are trying to exceed the stay limits w/out being noticed by the public or USFS. There are a 1000 low key squatters for every mess like the one pictured in the link.
Squatters are of 2 kinds. Locals that move their rig into position for dispersed camping early in the season and take it out as the snow flies. They basically commute to their RV for weekends throughout the season. This is a generational thing where these squatters start to teach the next generation that rules are for other people and unless you're caught it's all good. The 2nd group is seasonal workers. The expense and severe lack of housing for seasonal workers in mtn towns has led to more and more squatting.
There is no easy answer. As we become more and more overcrowded every day the search for solitude and peace is ever more difficult. It's forcing me and others to think of where and when can I go that I won't be bothered, instead of what great American landscape to see.
