In the past I have made a lot of visual NSFW content, mostly using Blender.. In that area, basically everyone has a Patreon and/or OF/Fansly/(Insert site here) in order to funnel additional supporter monies to them. In terms of a time commitment we are talking maybe 20-30 minutes of posing models and getting additional renders.. that's not very difficult.

Does this also hold true with erotica? I am vaguely aware Amazon itself doesn't allow you to directly link off-platform and books in the KDP program are locked down for several months.. but would it be cost effective to write original pieces for those platforms and then say "hey if you want to read my other work find it on Amazon"?
