MarsSeed [1] filed a deletion request for arenatracker-git [2]: This package is no longer useful to keep on AUR, because many of its legacy AUR dependencies are unbuildable and broken (e.g. the Python2 based opencv2).
Also it has zero votes/comments, so it seems it is not something that's in demand by users. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/arenatracker-git/
