Something I forgot to post earlier on the scola L-1 thing. Joseph mentioned looking to see who was online at the time, and I feel like there's a reasonable chance that he wasn't making that part up.
I wonder whether it's actually possible that his intention was to put scola to L-1 so that an off-wagon buddy would come along and drop the hammer. While people have already pointed out that no sensible scum would do that sort of thing D1, we already know that Joseph was being a bit obvious about his play, so maybe it actually seemed like a good idea to him at the time.
If that actually is the case, it implies that at least one scum was off-wagon at the time Joseph L-1'd scola:
scolapasta (6): Dylan32, A Drowned Kernel, LaLight, mail-mi, Calamitas, Joseph2302
which in turn implies at most one scum in {Dylan32, A Drowned Kernel, LaLight, mail-mi, Calamitas}, and at least one scum in {2.71828, Yuma, SpaceAnemone, WestCoastDidds, Swowl}.
