For the type of works I link my LiberaPay to, I don't have nor want tiers and rewards associated with them, as that forms a social contract where I am expected to perform more labour. I only want money from people who are thankful for what I've already provided, and I only want what they're willing to provide.
I suspect microscopic rewards like discord roles, a news letter, ect. do increase revenue, but then again you're managing a community.
I encountered issues with Stripe so that's been disabled, PayPal only, but PayPal doesn't auto renew. Again, I suspect I lost a considerable amount of money because of this. But again, taking money from people who wouldn't explicitly click 'renew' when they get the email doesn't feel right.
I also began offering Ko-fi as an option, however, because some people are uncomfortable with unfamiliar platforms.
