I agree.

Yes but you have to take into account both rate and time elapsed to
come up with a number. What I mean is that legacy resources, which
have no payment required, are probably abandoned at the same rate that
non-legacy/payment-required space is abandoned. BUT, there has been
little active reclamation of that space, so it has probably just built

Again, I am sure there is not enough space to help runout but I am
also sure that there is enough abandoned space to cause havoc from a
spam/malware/misuse perspective.
