From what I've seen of other Nazca lines, I am assuming that they (and I'm purposely using plural) are script kiddies exploiting a bug of some sort to gain permission to add routes in areas that they normally wouldn't have had permissions.
My guess is that they are using a script that draws a road then deletes it. Lather, rinse and repeat until you appear on the top of the point list.
The lines I've seen have definitely not been test or example lines. They're always straight as an arrow and very long with maybe one or two slight bends and never any junctions. They're always also red, with no information filled in.
Since I've started routinely deleting them, the rate of re-appearance has diminished. I'm going to assume they've figured out someone is monitoring the area and have decided that it wasn't remote enough anymore and have moved on to an even remoter area. Say Northern Canada or Outer Siberia.

Hayward, CA, Reno/Sparks, NV, Elko/Spring Creek, NV and apparently the N. NV section of Portola Valley, CA.
