The Software and Information Industry Association (SIIA) has announced that they will pay you 500 bucks if you catch a software pirate red handed. One thing you might try is to buy pirate software from eBay, and then you might become eligible for this cash.
In their "Don't Get Mad, Get Even" Campaign which is just launched, they have stated that
"The first 100 individuals who inadvertently purchase counterfeit software on an auction site, complete an application to participate in the “Don’t Get Mad, Get Even” program, submit the application to SIIA by no later than 5 pm EST January 30, 2008 and satisfy all the eligibility requirements necessary to participate in the program, will be eligible to receive up to $500 from SIIA. The payment is intended to help the buyer purchase a legitimate copy of the software."
The campaign will run from December 13, 2007 to January 30, 2008. However, there is a catch. The software must be one of the companies which has partnered with SIIA.
Too bad Microsoft isn't in their partnership list or I could have just bought another copy of Vista via eBay. But some big names like Apple, Adobe, McAfee, Nero, Oracle are there if you want to try.
