#BCTION #10F was an online exhibition held in parallel with #BCTION, an exhibition in which an entire abandoned building scheduled for demolition was filled with graffiti and other street art. While the real space walls from the first to the ninth floor were filled with graffiti, an imaginary floor "10F" was set up and used as the internet venue (a signboard was placed in the middle of the stairs leading up from the 9th floor at the actual venue to stop people from passing through, and the address was posted on it). In the internet venue on the 10th floor, the images that were uploaded one after another to #BCTION from the time of setting up were read in, remixed on the web page, and re-uploaded with the tag #10F. The aim was to intervene in the official hashtag from the internet side and influence the way the exhibition was seen on the internet. It also caused a reverse flow phenomenon, as people who visited the venue uploaded images as materials that could be easily used on 10F. Exonemo was unable to visit the exhibition site until midway through its period, so they created this system after thinking about how they could effectively intervene in the project via the internet.
