e. something else.

Because:

a. is wrong.

b. doesn't fix the problem, merely shoots yourself in the foot.

c. is impossible, stupid, and pointless to try.

d. has been proven to be implemented incompetently by Cox.

e. includes solutions known to work, including walled gardens, etc.

Again, you do not need to hijack someone else's domain name and redirect
portions of their namespace at one of your own servers in order to fix
this problem. 

Well, of course, that assumes that you're technically competent.
