I've played their game before. It's actually a lot of fun when you've been drinking. It's like "Apples to Apples", but with dirty themes and cards.
Anyway, I actually got one of these 1' squares of their private island in Maine. Looks like it got them in trouble for zoning and commercial use violations. I wonder if they'll fight it, since they apparently just gave a "license to use" rather than a real subdivided ownership to their fans. The Maine community is apparently demanding they take back the licenses and turn the land over to a "non-commercial" owner.
Seems like much-ado about nothing. I bet very few people have or will visit the island.

I second the game. Some of the cards will make you either blush or question your morals for putting them out there in the situations that come up...
Gawd I hate zoning.
