It's more complicated than that. Sitting arbiters were on the list. ****** No, it's quite simple. I made a bad block. No grand super-secret cabal ordered me to make it. And even if they had, list behavior is off-wiki and outside ArbCom's purview.
If you sincerely believe that list actions are blockable, then would you consent to a level 2 warning for WP:POINT and WP:AGF? What's good for the goose is good for the gander.
