The nature of SC and WC is different from Diablo though.
Even then, most people frown on the use of AutoIt and such in PvP (DII) because it would make dueling unfair, but in terms of duping and others... true, it will ruin the economy, but PvP-wise it actually helps people to get the expensive gear they want and can enhance the gaming experience.

(But we duped in the past only because...the enconomy was ruined anyway if we didn't, soo... )

At this moment, I don't think a lot of people would want to ruin the economy in DII, Ladder or not. In conclusion, I am against making a hack section.
