If you're interested in this sort of thing, you might also be interested in Archivy [1], which is somewhat similar but it (thankfully) doesn't upload your stuff to archive.org
FIY You just have to set the environment variable SUBMIT_ARCHIVE_DOT_ORG=False
Not uploading people's stuff to permanent, public archives seems like a good rule of thumb.
If it isn't already public (i.e., reachable by archive.org), it won't be afterwards?
I really wanna read this but can't find the thread, do you happen to have a link?
