Hmm, maybe I did get a little overzealous on your post. Sorry about that. I can't undo my flags because they are past the pay out date, but I can make it up to you with some upvotes.

My goal is to flag spam. I actually don't or at least try not down flag something just because I don't like it. I have a set of relatively objective criteria I go by when flagging. I flag for tag abuse, plagiarism, certain kinds of duplicate posts, fraud, really bad content (like child porn), blatant begging, and blog advertising spam.
