Through the efforts of @[email protected], the lemmy-safety tool can now run via docker, which should help you run it without having to mess with python on your end.
For those who don’t remember, lemmy-safety is a script you can read to clean up your pict-rs images from potential CSAM.
This was created in response to mass posting of CSAM on lemmy recently. It might be one of the reasons its a “non-existing problem”.
