Is it possible to see who created the link?

Hey Megan thanks for the reply!

One clarification: I did not delete any content. All docs are currently preserved just as they were.

Looking through my folder activity, there is one event where former atty (FA) created a new folder and began moving docs into it, but then FA deleted that folder in the same session. I have found no other activity by FA in my folder activity. 

If FA downloaded or transferred files or folders, would that action be recorded in activity history?

If I can rule out that FA did not obtain a copy of my content, I would have my answer that the links, regardless of who created them, were to my docs in my dropbox. And that answer would be all I need.
