A program that grants points for using Bing search, which users can redeem for gift cards, sweepstakes entries, or charitable donations.
I am wondering the same about points disappearing. I tried cashing in some of mine for a gift card, but MS wanted me to verify my identity but then wouldn't take my phone number because it wasn't an allowable "alias" whatever that means. I haven't tried again but I need to because I have a lot of points I don't want to lose. And just to add to my irritation last night I was 5 points away from the 100 for cell search and after doing about 150 different searches on Bing via Edge and Google it would not give me the 5 points needed to get to 100. I am/was so ticked!
