I'd say the only thing you know for sure is that the source is unknown
unless it is explicitly tagged. I wouldn't assume anything besides
that. There are people who don't upload their traces (i personally
always do) and who have all rights to not do it.

you can easily get this information by looking at the history (or even
render a custom map to display the age), but feel free to add it ;-)
