Constant-Content: Scam or Not? No Way, Not in My Experience

I've been so busy defending HubPages from being thought a scam that I've neglected Constant-Content, which some writers have found great success with, and which others have been unhappy with or not had massive success with.  Having just received notification that I recently sold a $125 article (of which I got about $80 as my cut), I've begun to renew my excitement with this article writing website.  I should say first, though, that I think I understand why Constant-Content might be thought to be a scam.
