1) “family” blogs- this isn’t just a problem on patreon but also exists on YouTube, tiktok, etc. this is when you can film your own children bathing or other settings and sell it as family friendly content. Yes, creepy men comment on these videos and it’s dubious about how or if the parents are exploiting their child— a much better coverage than this article is the Somewhere Under Neith podcast which explicitly explores how vulnerable parties are exploited and overlooked[1] (they also did a series on child marriage and where it is legal to marry children in the USA).
2) drawn or animated adult content - loli/shota shit, legal dependent on country, no actual children harmed here
I think this article performs multiple leaps of logic and cites anonymous sources for its more serious allegations. For example it assumes an off handed anonymous glassdoor comment “if half the child porn allegations are true patreon is in trouble” to mean patreon as a company is aware of and endorses any child porn on its platform. It could instead just be someone who saw the same tiktok the article points to alleging child porn.
(This isn’t to say there isn’t csam on patreon but I don’t think patreon is uniquely platforming csam based on these allegations. Unfortunately uploading videos of your own children in bathing suits and stuff without their consent is very legal and categorized as family friendly even.)
