I wish I could find this post again, but one company had a clever approach to the problem. If you can figure out which countries the cracked software is originating from, you can serve up a version of your page where you offer up a free, unlocked version of your app.

You're still losing out on sales, but cracked software often originates in those same low-income countries. They get to have their free copies, and it's a likely bet that your customers in wealthier parts of the world will just buy the license instead of attempting to crack it themselves.
