Right, that's what got me wondering. I've got an account on the flagship Pixelfed instance, and I started thinking whether that's a plausible use case - setting all uploads to private (or, I guess "unlisted" is the only available option) and effectively using it like Google Photos. I guess it's a bit of a stretch but my preferred attitude is to be open minded and generally to cheer on the activitypub projects. They are, in the end, a force for good.
