They don't follow that policy. I tried to re-register the account I lost access to, thinking while I might not have access to the data, folks reaching out to my old email would be seen -- it told me the account still exists.
I got a notification a month or so ago for an email I'd completely forgotten about, apparently last used around 2005 or 2006, that it would be deleted in a few months if I didn't log in. It seems haphazard but they do seem to be doing it.
So I can't reclaim it, but can't get in either.
