I watched some interesting videos about self-accountability for both people who have perpetuated harm (like myself) and survivors (which sounds way more victim-blaming then I think it actually is; judge for yourself though!).
In trying to do more research I came across this article on self-accountability and bought a few things (also this). I also checked out resources suggested by the videos from the NW Network, Creative Interventions, Bay Area Transformative Justice, and Just Practice from Shira Hassan.
None of this will make up for the harms I’ve perpetuated, but it will hopefully prevent future harms from happening, if nothing else.
