Yes. Bob was saying that there exists. I'm claiming there are cases
where there does not exist - i.e., not for all.
The issue is what to do with a paper published in the case I'm
considering; we all know what to do when you CAN safely anonymize.
However, note that you don't always know when it's safe - just because
_you_ can't correlate the info doesn't mean someone else can't.
