Comment 3 for bug 1079283

I think this bug is more about the fact that the concepts behind the privacy panel are not fully understood/explained.
"Don't record activity" is exactly what it means, it won't record "new" activity about specific types of files in a specific folder, but previously recorded activities still exist and will be displayed in the Dash.
We should either:
a) do a better job at explaining this panel.
b) change lenses to never display recorded activities if their recording is disabled in the panel, therefore considering it as a Dash blacklist (AFAIK, only the Videos lens is working this way).
