On 24 February 2022, BBB received recognition and praise across the globe for being one of the first sets of supporters to publicly show their support for Ukraine in the context of the Russian invasion that had begun that day. BBB members displayed several Ukrainian flags along with a banner that read "Support to the people of Ukraine". The image was subsequently shared on the Instagram stories of the football section of Bleacher Report, Manchester City left-back Oleksandr Zinchenko, and was the main photo in an article from Time magazine.[8] They also chanted "Slava Ukraini" (English: "Glory to Ukraine").
