It's never fun to be contacted by a legal department and be told that something you bought online is not rightfully yours. Still, this occasionally does happen in the case of intellectual property that has been misplaced and is not supposed to be resold. Example: The case of Reddit user Khemist49, who found himself in possession of a CD-ROM claiming to be the original source code for the game "StarCraft." Where did he get said disc? A box of "old Blizzard-related stuff" he bought on Ebay in April. Thinking he had something special, he posted on Reddit asking what to do with it.
He got the usual answers of course. Post it somewhere, be a god among pirates, etc... but Khemist49 did the unthinkable instead: He actually turned the game in to Blizzard. Of course, Blizzard legal was involved in influencing his decision, but this story is not without heart, for it has a happy ending. Upon returning the CD, Blizzard proceeded to shower him with a pile of gifts including a $250 gift card for the Blizzard Store, a Razer keyboard, and a lot of other goodies. Blizzard even offered to pay for Khemist49 to come to BlizzCon that year.
