Another form of activism would be to weed out uses of regexp as in http://www.mathworks.com/matlabcentral/cody/problems/944-create-incremental-spiral-without-using-eval-or-feval/solutions/new.
This problem is also working correctly again after a few-weeks glitch. Rescored the last few votes to get those right.
Is there a way to parse the code inside the regex and assign an appropriate size to it? That would seem like the most fair thing to do.
I believe this hack should be banned. It makes the code hard to read and creates a dummy small solution while not being the smallest (local minima that may not exist for the problem).
I had fun with this paradox! ;-)
