I suggest adding the “I do not want to vote” button to all polls. So that you can see the results without your voice. Example: I want to install Linux. I see a poll: “How do you use Linux at home?” There is no “no” option. And I want to know what the majority uses - it will affect the choice. Had such a button - I would just look at the results. Of course, after clicking this button you cannot vote in this poll.
