I wouldn't normally notice a robot I've only met twice,* but this one's got an oddity: it only eats PDFs. First saw it in May when it ate all three PDFs from an extremely obscure directory (took it a month to find them). Just showed up again to eat a brand-new PDF that's only been indexed a few days.
What do you suppose it does with them?
And, for that matter, how does it find them? Does it hit up the search engines every 24 hours, or possibly every five minutes, for a list of newly indexed PDFs?
* Found one recently that had been slipping under the radar almost daily for several months.
