How do software manufacturers protect against software piracy?
that depends on how you approach the issue. who exactly are you
trying to control? if you are trying to control yourself, just stop
pirating. if you are trying to control people you are responsible
for, such as your children or employees, you should verbally make
it clear that software piracy is unacceptable; let them know that
if you catch them they will be punished; hope that they take heed.
if you're trying to stop somebody whom you can't control you can
contact the Business Software Alliance at bsa.org and they'll be
happy to help!
