A meticulously-crafted post made to look confidently ignorant, written by an intelligent person is no different from a confidently ignorant post written by a confidently ignorant person. They both spur argumentative (i.e., non-substantive) posts. One is a troll by any definition; the other most people would also call a troll, even if the author didn't intend for it to be. Likewise, if someone intends to write a troll and instead writes a devil's advocate post which spurs substantive debate, then it's not really a troll, even if the author intended it to be.
