“World War III” started trending on social media. Young men suddenly recalled registering after their 18th birthdays, many having done so while applying for college financial aid. One Twitter user posted that he had blocked the account of the United States Army, with the (faulty) reasoning that: “They can’t draft you if they can’t see you.”

Interest was so high that it apparently crashed the website for the Selective Service System, the independent government agency that maintains a database of Americans eligible for a potential draft. “Due to the spread of misinformation, our website is experiencing high traffic volumes at this time,” the agency said on Twitter, adding, “We appreciate your patience.”
