Mark Zuckerberg is worth about $250 billion. On Kauai his lawyer called a Native Hawaiian woman to ask how it felt to get $800 for land she never knew she had. Her cousin had already sold her share for $400 to Northshore Kalo LLC, thinking the buyer was a taro farmer. It was Zuckerberg. In 2014 he paid a reported $100 million for 700 acres on the north shore and built a rock wall around them. Inside sat kuleana, small parcels Hawaiian families inherited for generations without wills or deeds. In December 2016 his companies filed quiet title lawsuits against more than 100 people to force those parcels to auction. Shannon Buckner owns land on the other side of his fence. If she walks onto it, she says, she gets arrested for trespassing. Teri Ferreira found out who the buyer was after the sale. "I was mad, I was upset, I felt deceived," she says. "He can offer me $100,000, I won't take it." After the backlash Zuckerberg apologized in the local paper and dropped the lawsuits in January 2017. "It's hard to save your land when you have a billionaire fighting you for it," another descendant says. Teri says that land is not for sale.
