Identifying GPS traces

Is there a way to identify the uploader of a specific GPS trace? I have seen some GPS track logs in one particular area but they have not been tagged with any of the relevant tags or descriptions I can think of. I would like to coordinate mapping activity with whoever is actually active on the ground in that area.

Any ideas?

No, this is not possible. The only way is to use Google and search for tags in the traces section afaik.
