When two robots face off in a concrete ring to battle to their brutal, oily deaths, no animals are harmed in the process. But YouTube has been taking down videos of Battlebots and issuing strikes against their creators, citing animal cruelty.

As first spotted by YouTuber Maker's Muse, YouTube has taken down videos of robots doing combat after mistaking them for videos that show "deliberate infliction of animal suffering." f YouTube has confirmed to Motherboard that it removed the videos in error, that the videos have already been restored, and that YouTube has no policy against videos of robots fighting.
