Good thinking!  I summarized the methodology on the graph page as: The
graph above is based on sanitized Tor web server logs [0]. These are a
stripped-down version of Apache's "combined" log format without IP
addresses, log times, HTTP parameters, referers, and user agent strings.

I guess we'll write down the sanitizing process in more detail once we
make this part of CollecTor, but that may take a few more weeks or
even months.

If you spot anything in the data that you think should be sanitized
more thoroughly, please let us know!
