In an interesting move, Blizzard got the idea to drop the hammer on videos of Overwatch characters that do naughty, naughty things with each other. This doesn't seem to relate to artworks, but more about the videos that use the game's assets to depict the Overwatch characters getting down and dirty. This includes but is not limited to DMCA take downs against several folk like the Reddit user "Spornm," which is but one user cited in the source below.
Obviously because this is the internet, we know for a fact this isn't gonna go anywhere, and you can bet there'll be re-uploads on 100's of sites and blogs across the world within moments of a sexy video being posted. Or at least some GIFs. Silly Blizzard, you forgot one important thing here...
The internet is for porn
