EFF has, on multiple occasions, specifically defended Kiwifarms, a site which unabashedly exists to turn people into hate-celebrities, with some members having kept "kill counts" of harrassed targets who committed suicide. The site is also known for spreading absurd false accusations, which has at least as much negative impact as AI revenge porn.
The EFF is not consistent in its principles. It has partisan bias. However, it can still be worth situationally supporting for certain causes.
