Great but has an issue

I love Recolor! Its so fun to color and then post if you have an account. However there is one problem: coins. Instead of a membership, you can earn coins by watching videos (10 coins per exclusive pic). However, they say they never have ads! That really ticks me off. Please fix, Recolor!
Happy 2018 ?
