  The solution to abusive reputation providers is well-known, at least
outside of the computer world.  See various "eco-friendly" logos, and
how their chain of responsibility (i.e. certification) is structured.

  You need at least a two-level reputation service.  One which
interacts with customers, and the other which certifies the reputation
services.  This structure has been demonstrated to solve a lot of
issues with abusive and/or corrupt reputation services.
