Tech Report: provide a list of example URLs

[rviscomi]

Suggested by @benmccann: It would be incredibly helpful to have a list of origins or at least a random sampling of a few dozen each time I run the report. If I can see some actual sites it will give me a lot more insight as I can manually check a number of the things below for a small sample of sites.

@benmccann please share what would you like to verify with sample sites.
