Why do I see words like "Coach" and "Nike" marked as spam?

SpamZilla has a large list of "bad spammy words" that it uses to detect spam within the domain, history and anchor text.  The words in this list we've built up over a few years from our daily spam checking.  Though we understand this feature might be a little aggressive, so we're planning to change this functionality and allow users the ability to select their own "bad spammy words" list.
