  So your reputation doesn't recover when you move the domain
elsewhere?

  Wow, you hold grudges for a *long* time.

  Which does something else entirely, so comparisons aren't really
appropriate.

  And no one, of coure, will make the connection between "bad IP" and
"your domain is at that IP", so it will be impossible for anyone to
decide that the IP's bad reputation will affect your domain's
reputation.

  Where SPF ties reputations to domains, CSV ties it to IP's.  Since
domains are hosted at IP's, it's not a terribly large leap of faith to
use CSV to tie reputation to domains, too.  And CSV can't prevent this
leap, so we can guarantee that people will be using CSV to affect
domain reputation.

  At that point, much of your argument against SPF applies to CSV.
