With "imports", such as with the web "bulk" button facility, there is no subscriber add/delete entry in the changelog ... so no changelog entry for your person of interest is not proof of former subscriber status. (sorry for the double negative!).

If the list had a changelog active since before the "some time in the past" you're interested in, the subscribe/add signoff/delete activity would be listed in there. Changelog reports are available via the web interface.
