Perhaps it would be more intuitive to write 'undo' instead of 'refuse'. The turn-based-server page, which was not specifically made for Refusal Chess, considers the 'undo' a normal move: it wrote ee7 (SAN for e6-e7; it adds a disambiguator to indicate which Pawn moves to e7, because none of the black Pawns can move there legally). It will disambiguate the moves in the normal SAN way, though, assuming that you know which color is performing the move. Which in this case is not true.
