Cards Against Humanity, the naughty party game, is taking on Elon Musk, the man said to be the richest in the world, and his rocket company.

Last Thursday, CAH filed a $15 million lawsuit in Cameron County, Texas against SpaceX for trespassing on land they own near the Mexican border. The company purchased the land in 2017 as a protest against then-President Trump’s border wall, intending to keep the land in its natural state and refuse any further development.

No wall was ever built there, but around six months ago, SpaceX and its contractors began using the property as its own, clearing the land and leaving behind equipment and supplies, ignoring a fence and no trespassing sign posted by the Cards Against Humanity company.

The company is asking the court to award them up to $15 million to cover “the cost to restore and repair the Property, the diminution in the Property’s fair market value, the reasonable value of SpaceX’s use of the Property, the loss of goodwill, damages to CAH’s reputation, and other pecuniary loss and actual damages suffered by CAH.” The suit also seeks punitive damages.

Cards Against Humanity were notified of SpaceX’s activity on their land by a homeowner in the area, one of many inconvenienced or worse by SpaceX’s activity in the area, which closed roads and beach access to residents who own property and have lived there a long time.

The company has vowed to share their winnings, if there are any, with the 150,000 subscribers who helped raise money for the purchase through a crowdfunding campaign that took place in 2017.

The lawsuit said that “SpaceX has never asked for permission to use the Property, much less for the egregious appropriation of the Property for its own profit-making purposes,” and “never reached out to CAH to explain or apologize for the damage caused to the Property and CAH’s ownership interest therein.”

Cards Against Humanity also created a webpage dedicated to the lawsuit, which you can access here. The company posted on this page that in lieu of money, they “will also accept Twitter.com as compensation.”
