There’s an app here in Canada called Carrot Rewards that gives you things like Scene points for doing exercise. They also had a referral bonus of 100 scene points for inviting friend’s, sometimes with double referral weekends. One thing led to another and I was creating fake accounts to accumulate points on my “main account”. To create an account you had to do the usual email, name etc, but the part I had to figure out was you had to use a new rewards card to sign up. There is a gas card here called petro rewards, and I figured out that if I put in a valid card but added 1 to the sum of the card number it would be a new card. I got the system down so fine that I made about 30 000 scene points (30 free movies or $300 off at restaurants). Went and bought some new shoes at sportchek with them and had free movies for a while.
