I'm struggling to understand why cracks and patches are needed on pirated applications; particularly those which are protected by a serial number. As an example, if I go to a store and buy some software that I know is protected by a serial number and then create a raw image and share that along with the serial number with the rest of the world then clearly there is no protection at all.
So, since most applications/games use serial numbers as verification, why are cracks needed if the above would nullify all protection?
p.s. To the mods, despite this question containing enough flagged words to make your filters scream, I'd appreciate it if you don't go just deleting this without first questioning me. I'd find it very ignorant and presumptuous if it were to be deleted without at least letting me give reasons why it should stay. Thanks. :)
