If you have any google juice at all and you use the word "crack" in an entry, you are at high risk for getting lots of dumbasses coming to your site looking for illegal keys to whatever software it is that they found on some shady bittorrent site. Some of them will even be brazen enough to leave you comments on random entries unrelated to their pursuit asking you for the keys despite the lack of relation of that post to what they want. Sometimes clues are thin on the ground.
