Overwatch fever has, perhaps inevitably, spread into the world of porn, and Blizzard appears to be fighting back.

Pornographic video aggregator Pornhub reported earlier this month that searches containing "Overwatch" jumped 817% upon the launch of the game's beta.

The most popular search related to Blizzard's online hero-driven shooter is "Tracer," possibly thanks to the scandal surrounding that character's butt-centric victory poses.

But many of the videos available on such sites are animated, via Valve's Source Filmmaker, using Overwatch's own character models, ripped straight from the game.

As a result, copyright notices have been served to porn animators over the stolen game assets.

Those notices come from Irdeto, an internet security company likely hired by Blizzard to monitor and combat IP theft on the Internet - if not specifically in terms of pornographic content.

One creator took to Reddit to compare the move to removing fan art, despite fan art typically not containing actual game data; they also called for the Overwatch porn community to resist the legal notices.

Overwatch is available now, sans porn, for new-gen consoles and PC.
