Looking to waste a bunch of time? Try GetRef!
After spending some time there I realized that you can waste a bunch of time gaining credit, but you have a 50/50 chance of just spending your time to get credit on things only to have the person scam you by taking your referral bonus on their site and never crediting you for it. There’s no honor system in place, no way to dispute a rejection, and no way to report this abuse. Run. Run far away! If you want referrals, there are much better ways to get them. Don’t waste your time on GetRef.
