During the Warhammer 40,000 crossover promotion in 2020, the game's publisher Wargaming came under scrutiny after it was made aware by Twitter user Darren Bogus that they were sponsoring controversial YouTuber Arch Warhammer to help promote it. Arch Hammer is known within the Warhammer community for his misogynistic, racist, and hateful remarks. In a statement from Wargaming on July 3rd 2020, they issued an apology and claimed that sponsoring Arch was due to "human error" and had since cut ties with him. They even admitted that they were warned beforehand by Warhammer's owners Games Workshop not to collaborate with him but had failed to follow their request.
