I'm not sure if you're aware, but after Tumblr introduced polls, it didn't take long at all before it was fairly common practice to include a [see results] option or a nonsense word option to filter out lizardmen responses. I'm not sure how well it worked in practice, but there's a lot of polls where that option predominates (e.g one very popular post a couple weeks back surveying sex frequency where the virgin/celibate option got like 60% of the total vote)
