I created a survey for new guests to our facility. I added a coupon at the end of the survey as a reward in thanks for completion. A reward for that singular person and not the entire planet. Be careful with coupons. No option to "turn off" sharing. My reward for one person turned into a great deal for a lot of folks. Even with selecting "turn off" sharing. Not possible to reward one individual for taking time to give you feedback!
Thanks for posting this feedback. I am sorry to hear this happened but appreciate your feedback. When you sent the survey did you send to a list or just the one person and it was shared from there?
