Between January and July 2015, the period in which Yahoo allegedly implemented the program, the company says content from 21,000 – 21,499 user accounts was requested under the Foreign Intelligence Surveillance Act, and content from 0 – 499 accounts was requested via National Security Letters. However hundreds of millions accounts may have been accessed by the customized program. The situation produced strong reaction. “Forcing a private sector company to search emails is even worse than the NSA’s bulk collection program because now the federal government is seizing and searching content, not just meta data, without a warrant,” Congressman Ted Lieu said. “This is big brother on steroids and it must be stopped,” he added. “Yahoo is a law abiding company, and complies with the laws of the United States,” a Yahoo spokesperson told.
