SportsTeams, the obscure sports-specific Social-Tools extension from ArmchairGM meant to be used with UserStatus to provide the sports fan networking functionality, does not check for the anti-CSRF ("edit") token in Special:SportsTeamsManager and Special:UpdateFavoriteTeams.
Similar checks were added to Special:AddFan and Special:RemoveFan in 46a0054e0d0c5f15ecf10e6a428e73daf6608f4f (September 2020) and to the uploading special pages even earlier, in bccf8758c699f2ecb7b0f43a5f5606d2ec59beb2 (April 2020).
