Thanks Lee for the excellent explanation.

I have created block lists in this manner before and they work great.

I was trying to come up with a way to use a wildcard or some regex solution
to block anything "tile" related.  It seems like either "tile" or "
tile-x.com" is usually involved.

I won't be able to catch them all and I cannot find a list of all of these
hosts.  I know they only downside to this is there might be false positives
but I am willing to give it a shot.

Then I can search the log files for blocks related to this and we can
create the first ever "Live Tile" blocklist and share it on Git.  I would
love that!

Also, I didn't have to set my Windows 10 PC to use the proxy the way you
mentioned. I have Privoxy setup in all of the browsers and somehow the OS
is pulling it from there. Seems to be working?!

Thanks again.

Robert
