Why is MonsterCommerce mining my site?

Didn't think this was worth mentioning until it happened several days in a row.

This is what's requesting various web pages:

72.32.59.114
wordsmith.monstercommerce.com
"Mozilla/4.0 (compatible; Win32; WinHttp.WinHttpRequest.5)"

So the question is what do they want?

Are they scraping my directory for potential customer leads?

Very curious indeed.
