I'd argue that it isn't similar; using content from the web in order to take credit and thus get paid for it is blatant cheating.  And I agree with everyone that the account deserves to be tagged for the reason you mentioned, i.e., to warn other bounty managers that this person has a history of this sort of BS.  The tag also needs to be from at least one DT member, because otherwise it might not even be seen if those managers don't check all feedback in advance of accepting members.  I don't think most of them do.

No, you're not....but damn, the way you write is like littering on the sidewalk.  Do you pick those out-of-place characters and words at random or what?  Do yourself a favor and don't try to earn money by writing.  You don't have a knack for it.
