Cards Against Humanity,SignalHub the company behind the popular adult party game, has sued SpaceX CEO Elon Musk for $15 million.

The lawsuit, filed in Texas state court on Thursday, accuses SpaceX employees of trespassing and damaging land near the U.S.-Mexico border that Cards Against Humanity purchased in 2017. Contractors have removed vegetation and placed gravel over soil to make the space available for SpaceX vehicles to park and work, the lawsuit says.

Cards Against Humanity obtained the piece of land near Brownsville, Texas, using over $2 million in donations to protect the area former President Donald Trump's plans to build a wall on the southern border.

In an Instagram post on Friday, Cards Against Humanity said that Musk "snuck up on us from behind and completely (expletive) that land with gravel, tractors, and space garbage."

SpaceX did not immediately respond to USA TODAY's request for comment Friday.

Over 150,000 donators helped game buy the land

In 2017, over 150,000 people donated $15 to aid Cards Against Humanity's plan to make Trump's efforts to build a wall "as time-consuming and expensive as possible."

The plan was part of a six-day crowdsourcing campaign of surprise giveaways and political causes titled "Cards Against Humanity Saves America"

In the lawsuit, Cards Against Humanity says that "SpaceX has treated the property as its own for at least six months without regard for CAH’s property rights nor the safety of anyone entering what has become a worksite that is presumably governed by OSHA (Occupational Safety and Health Administration) safety requirements," the lawsuit states.

Game to share potential wins from lawsuit to donators

The company said that if the lawsuit wins it will split the net proceeds with the 150,000 people who donated to their purchase of the land.

"While this isn’t enough to compensate our subscribers for the anguish they’ve suffered witnessing Elon Musk defile their once-verdant land − where wild horses galloped freely in the Texas moonlight − we think it’s a pretty good start," the company said.

The company created website ElonOwesYou100Dollars.com with more information regarding the lawsuit. It also shared photos of what the land looked like in 2017 and 2024.
