What is squider?
 

And I don't mean the squid/squirrel thing.

I've been seeing odd batches of hits with squider in the user-agent [ ex: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/27.0.1453.110 Safari/537.36 Squider/0.01 ] - anyone know what this is/does? I don't want to block honest users, but if it's a scraper or some shit like that then it's time to go.
