YouGov survey question

Sorry this isn’t really related to Andrew Yang but I wanted to ask my fellow Yanggang. I just signed up for YouGov and recently noticed that there are rewards like gift cards and stuff that you can redeem after a certain amount of points from surveys. I had just noticed this and never saw anything about it in this sub and wanted to know if it was legit? Since recently lots of people have been pushing for people to sign up for YouGov and many getting surveys voting for Yang maybe someone could answer if they’ve gotten to redeem a reward and if it’s legit. Only reason I bring this up is because if they are legit it could help motivate more people to sign up and possibly vote for Yang, in a YouGov survey, which many have been qualifying polls.
