I am an illustrator and an artist. I've been using Redbubble since 2018 and I have more than 1K designs uploaded. I never really earned a lot of money but as creative job it was a good side hustle. Last year RB decided to implement a tier system, dividing creators in 3 tiers, with no explanation of the rationale underlying. You can be demoted (and so subjected to fees that are not clearly explained and are extortionate) without a valid reasons, without warning and with no possibilities of appeal. Strangely the accounts demoted are often the high earners, so that RB can take another gabelle on the already meagre margins artists have. Prints quality have also deteriorated, prints tend to wash out much quicker. Pity - I used to love RB for the interface easiness, but their questionable ethics made me regret to have given so much time to create original work for their platform. I have since decided not to upload anymore.
