I initially tried to used data jam to try and check who my mutual followers were on Instagram. Datajam does not provide that information. I had to sign up for a "7 day free trial" just to find out it didn't offer what I needed. I then got charged 15 dollars USD for a "free trial" and still haven't had my account deleted, despite email correspondence saying they will delete the account. The interface is convoluted and not user friendly and I think they are purposely doing this to try and scam more money off of you.
