This week, Anonymous is continuing their war on ISIS with a plan to spam their online hashtags with "rickroll" videos, the music video from Rick Astley 1987 hit song "Never Gonna Give You Up." The "rickroll" meme was started on 4chan in 2007 and has been a favorite of the internet ever since.

Following the terrorist attacks in Paris earlier this month, Anonymous declared war on ISIS and began taking down their twitter accounts. As we reported last week, the group took down over 5,500 Twitter accounts that were associated with ISIS.
