The biggest difference is that metadata features are not so useful. Also, the strongest feature set is the combination of sentiment, bad words distribution, POS, metadata, and punctuation. This suggests that paid trolls are smart to post during time intervals and days of the week as non-trolls, but they use comments with slightly different sentiment and bad word use than non-trolls. Features based on words are also very helpful because paid trolls have to defend pre-specified key points, which limits their vocabulary use, while non-trolls are free to express themselves as they wish.
