Sometimes it's hard to know whether someone's a troll or simply unreasonable. It's worth it to try to reason with them once or twice but just block if they won't listen to reason (obviously with neutral block summaries). I've found that the most effective trolls are the ones who know how to make it look like they're trying to do good but never miss an opportunity to get under someone's skin. But yeah, continuing an argument with someone ad nauseam not only isn't effective, it just feeds the trolls in some cases.
