One more thing: The fun in the Puzzle Portal is supposed to be mutual. It would not occur to me to keep setting puzzles if I wasn't enjoying it. But on the other hand, I would expect solvers to solve puzzles because it is fun for them as well, which might not be the case if the puzzle is broken. There have already been discussions about how the avalanche of new puzzles ("Sudoku flood") takes the fun out of the Portal for some, and I cannot imagine things to improve if all the broken puzzles would remain active just to keep the discussion going.
