The US government is seeking to unmask every person who visited an anti-Trump website in what privacy advocates say is an unconstitutional fishing expedition" for political dissidents. The warrant appears to be an escalation of the Department of Justice's (DoJ) campaign against anti-Trump activities, including the harsh prosecution of inauguration day protesters. On 17 July, the DoJ served a website-hosting company, DreamHost, with a search warrant for every piece of information it possessed that was related to a website that was used to coordinate protests during Donald Trump's inauguration. The warrant ... seeks to get the IP addresses of 1.3 million people who visited [the site], as well as the date and time of their visit and information about what browser or operating system they used. The warrant was made public Monday, when DreamHost announced its plans to challenge the government in court. The government has aggressively prosecuted activists arrested during the 20 January protests in Washington DC. In April, the US attorney's office in Washington DC filed a single indictment charging more than 217 people with identical crimes, including felony rioting. The Electronic Frontier Foundation, which has been advising DreamHost, characterized the warrant as "unconstitutional". "I can't conceive of a legitimate justification other than casting your net as broadly as possible," senior staff attorney Mark Rumold [said]. "What they would be getting is a list of everyone who has ever been interested in attending these protests."
