You might be seeing a survey like the one above on top of quizzes on Sporcle. The survey is there to provide users with a way to support the site, and improve their ad experience. It takes a few seconds to complete, and it asks you to answer one or two questions. Once you take the survey, you won’t be asked to take another one for at least 24 hours, and you won’t see ads for 24 hours as well.
Support from users like you is really important to the continued operation of Sporcle. We are not a large digital media conglomerate with endless resources. We are a small business here to humbly serve the world of trivia lovers. All we ask is that you make a contribution to the site by either viewing ads or answering a couple quick survey questions.
