Nope. Archive.org has a part where you can upload videos, it is separate from web archive. ISIS uses archive.org almost exclusively for sharing their propaganda videos (all the executions, war videos, etc.). It's not the web archive they are using for this, it's the video archives. I am not sure why are they doing that; probably because the barrier for using it is low and they don't delete the ISIS propaganda so much as other websites (like youtube). Other website jihadists love to use is justpaste.it for text
