The developer of popular party game "Cards Against Humanity" is accusing Elon Musk's SpaceX of trespassing and damaging a piece of land the company owns in Texas. In a lawsuit filed this week in state court, the Cards Against Humanity organization claims that SpaceX has essentially been treating the company's property in Cameron County as its own for at least the past six months. The lawsuit alleges that SpaceX, which has acquired other parcels of land near the property, has been placing building materials like gravel and other debris on the land without permission. SpaceX did not immediately respond to a request for comment.

The Cards Against Humanity organization purchased the land in 2017, which it said was one of its stunts in opposition to former President Donald Trump's border wall construction, with 150,000 people donating $15 each to the effort. Cards Against Humanity said the land has remained untouched for years. The company also said it has a “no trespassing” sign to warn people against stepping onto the private property. The company is seeking $15 million in damages, including the loss of vegetation on the land.
