Viacom did a general search on YouTube for any term related to any of its shows, and then spammed YouTube with 100,000 DMCA take-down notices alleging that all of these clips infringed its copyright and demanding that they be censored off the Internet. YouTube made thousands of clips vanish, and sent warning notices to the people who’d posted them, warning them that they were now on a list of potential copyright infringers and telling them that repeat offenses could lead to having their accounts terminated.
