Magellan

Asked for roots.txt, then ignored same six minutes later. From a .res.spectrum.com Host, with the full UA simply: Magellan

Huh. I have no record of a Magellen UA. I see it is listed as a browser plugin/extension:

Magellan Active Browser Plugin (free) download Windows version
The Magellan Active Browser Plugin is used by the Magellan Active Web Widget to communicate with Magellan Fitness devices connected via USB. It also gives 3rd party websites the ability to develop browser-based tools for interfacing directly with Magellan Fitness devices connected via USB.

It doesn't sound like the kind of extension/tool that should be requesting robots.txt - but it might have been 'altered'?

Shades of NetScape! Whew! That's a trip down memory lane. :)

This current bot, however, has not appeared here, so thanks for the heads up!

Another one this morning, this time from a .socal.res.rr.com address. Very similar hit pattern also with curious time delay: asked for robots.txt (not roots.txt:), then ignored same four minutes later.
