While creating a maintenance headache whenever www.snuggie.com and/or
www.r-9.net happen to modify the list of addresses they resolve to.
This "solution" creates problems of its own; it is no more a "real
solution" than the other. The only real benefit I can see to it is
that it doesn't involve fixing the underlying lack and thus requires no
effort from the rest of the world, and even that is a benefit only to
that "rest of the world", not to the person you are offering it as a
"solution" to.
