Point of note: Skip is the first to claim an item, in post #100. So before even ADK's plan, Skip is out there claiming stuff. Sounds like a way to goad out other claims, which is scummy.
He also continually clarifies himself about his "I have an item to give to someone plan." I find myself correcting my plans and finetuning them unnecessarily more as scum so I don't get caught with a bad, scummy plan.
Before skip goes for me, he's not pushing a 1v1. He's keeping his options open, asking others about what he should do, etc. Not until after I post does he vote for me, and he does say he's going to leave it there for the rest of the day. So he pushes the 1v1 more than I thought he did, but what else does he do at that point?
He also allows me to claim the item first, leaving all his options open again.
Also, his defense at post 316 is perfect for tomorrow when I flip town. "Come on, you think I'd do this as scum? I'm not that dumb." It's a bunch of WIFOM that doesn't turn out to be a good defense.
Also there's his unreasonable expectation of me, which Galz pointed out, that no other person who posted a list said "Whoa this is a potential 1v1, we should look into this." Not necessarily alignment indicative, but it's still there.
