Banksy Did It Again (Guilty or Not ?)

The famous grafitti artist Banksy, who recently had a major exhibition at the Bristol Museum, has supposedly stenciled over a work of 1985 by Robbo who is a reference from the grafitti artists of the 80's.
This act has triggered some controversy among the community and The Art Inquirer wonders about the causes that may be behind this public stunt.
It's not common for an artist to repaint over another artist's work without a plausible reason for it, so maybe in the near future we may update this article with further development.
Illustrating this article are the photos in the following sequence: original work by Robbo; Robbo's work with Banksy's painting over it; Robbo's repaint and modification over Banksy's work.
