Uh-oh. I agree with Blakeyrat on something.
It is the courteous and proper thing to do to ask someone's permission before using their work. For example, I only use code snippets online that the author gives express permission for, and I credit said author. If they don't provide express online permission, I attempt to contact said author. I can definitely see Blakey's frustration there. Then again, common courtesy and common sense aren't very common in this day and age.
