"Revenge porn" in this case being things the people involved willingly posted to the public or to their OnlyFans, which was then leaked. Unfortunately for the latter, pics of someone being an ethot are a commercial product and protected by fair use, and for the former, we have been told for the past 20 years to assume that the moment it's on the Internet, it's there forever. If my wife and I broke up tomorrow and I posted a pic she sent me to tease me when I was at work ~2 years ago, that would be the image in people's minds of revenge porn, for example. The attempts to expand that definition to "sexually explicit images, at all, for the purposes of humiliating someone", are the umbrella under which Kiwifarms would be said to host revenge porn. As pretty much anything on Kiwifarms is just what people have already said on clearnet in the open with archives, the expectation that the images and videos in question were to be kept in confidence is simply not there.
