    The very design of a checksum makes it useless for this purpose, as any two even mildly different files should produce unique checksums. If they didn't, the checksum wouldn't be able to tell if data had been corrupted in the first place.

    In other words, a minor and (relatively) simple alteration to the file would render the check useless. It isn't significantly difficult to alter a file ever so slightly as to make it produce a different checksum, certainly not enough so that using checksums will prevent the spreading of pirated files.
