I've had a similar thing happen, I went elsewhere because I'm people-phobic and don't want to waste time where some other yahoos have blown all the animals out. Having said that I think you should hunt it because you definitely have a leg up on them and as someone else stated their pressure could help you. I would have a backup plan though because they could run all the animals out of the area pretty quickly and you may need to switch gears.
Long term camps, couple places I've been in Wyoming we hunted for a solid 10 days and saw wall tents in prime camping locations that never had a vehicle visit the entire time, no tracks in the snow at all. Campers covered in snow that look like they'd been there for months, etc. It's definitely a problem and should be addressed by the FS for the rules. There's been a couple times I really needed a decent camp location and had to back out a mile or so because of these squatter camps.
