I second that. It makes no sense that the same button works for expressing opinion on payout and for tagging spam. That's some bad UI right there.
To many the term "flag" is offensive. If there was an upvote and downvote voting scale in the same interface, people wouldn't get as hurt by said flagging. I know I wouldn't. But as it is now, flagging by users who have more power than they can use feels like a kick to the face, especially to newcomers who invest a lot in their work.
