The best way to prevent someone from ripping your code is to made it so hard to follow that the person can tell what you are doing, a good way to do that is to do something like this:
Code:
alias myalias {
  var %cats = 5,%dogs = 17,%birds = 2783
  while (%cats <= %birds) {
    myalias.cats %cats %dogs %birds
    inc %cats %dogs
  }
  var %birds = $calc(%cats * %dogs / %birds)
  echo -a %birds
}
alias myalias.cats {
  var %birds = $1,%cats = $2,%dogs = $3
  while (1 <= %dogs) {
    dec %dogs %birds
  }
  echo -a %dogs
}

That code was easy to read right? But if I do this it makes it nearly impossible to follow!
Code:
alias myalias {
  var %O000000OO0 = 5,%O000000O0O = 17,%0O0O0OO0O0 = 2783
  while (%O000000OO0 <= %0O0O0OO0O0) {
    O0000O00O0 %O000000OO0 %O000000O0O %0O0O0OO0O0
    inc %O000000OO0 %O000000O0O
  }
  var %0O0O0OO0O0 = $calc(%O000000OO0 * %O000000O0O / %0O0O0OO0O0)
  echo -a %0O0O0OO0O0
}
alias O0000O00O0 {
  var %0OOO00O0OO = $1,%0OO0OO00O0 = $2,%0O0O0O0OO0 = $3
  while (1 <= %0O0O0O0OO0) {
    dec %0O0O0O0OO0 %0OOO00O0OO 
  }
  echo -a %0O0O0O0OO0
}

Just be sure to do this _after_ you are done writing the script, and be sure to save an orginal copy. Oh yeah, don't be surprised if your scripts don't get submitted places if you do this, because it's a very lame thing to do.
