This raises an interesting question: should email addresses be private? Addresses of buildings aren't private, and they're somewhat analogous as with many computing concepts. (Aside: Before spam filters were quite good, it was typical to avoid scraping of addresses by mild obfuscation, but I think those days are gone, and this is distinct from privacy anyway.)
If someone wants to upload and never be found out, then they need to use a throwaway address in any case, lest they be providing their "private" address to the administrators of the service without explicitly forbidding further disclosure. If I say something to Alice without demanding that Alice keep it from Bob, then I implicitly don't mind if Alice tells Bob what I said.
