Permanent copies accessible to anyone
As a data hoarder, I would say this is one of the most efficient and beautifully working web clipping services that I have encountered.
However, it seems that raindrop.io stores its permanent copies in publicly accessible manner, making it possible to access what other users have archived. Every permanent copy has the same address format and it's very traceable and open to public access (e.g. google "site:s3.eu-central-1.wasabisys.com"), which raises serious privacy concerns. Please make it a default option to have such addresses private.
