SAN FRANCISCO — Web service provider DreamHost is turning to an online litigation crowdfunding platform to help cover the costs of challenging a U.S. Department of Justice warrant that seeks information about visitors to an anti-Trump protest website.

The company is seeking to raise $10,000 through its campaign on CrowdJustice, a kind of “Kickstarter for lawsuits” site that originated in the U.K. and launched operations in the United States in January. The cutoff date for the funding campaign is Sept. 16.

By mid-day Friday, the DreamHost campaign had drawn $940 from 13 donors, according to the site. No money is actually donated unless the target is reached.
