Well long story short I have been writing a fan fiction for a while (The fan fiction takes place in the 'please don't tell my parents i'm a supervillain' universe) and some of my readers asked how they could support me. I want to give them something as a reward so I was thinking of earlier access(Before I finish proof reading.) however I am afraid that this might be considered monetization and be considered a copyright infrigement.
As such what I wish to ask is that is it copyright infrigement or can I give early access to my readers?
