C. If you claim to have supporting evidence available online, but instead of linking to it you say “Look it up yourself,” you lose. Similarly to the banning thing, “look it up yourself” clearly means “please please please don’t look it up yourself.” It’s an admission of failure.
D. If you invoke the name of a logical fallacy without explaining its relevance, you lose. Logical fallacies are not Harry Potter spells. You don’t just get to shout them out and wiggle your wand to make magic happen. Plus, there’s a logical meta-fallacy: Just because someone’s making an error in reasoning doesn’t mean they’re wrong.
E. If you claim to be winning, you lose. This should be self-evident: If you’re so desperate that you have to tell someone you’re winning, you’re obviously not. http://www.wired.com/underwire/2012/12/alt-text-internet-arguments
