Re: Purchased IPv4 Woes

[Justin Wilson <lists () mtin net>]

Then you have the lists which want money to be removed.  I have an IP that was blacklisted by hotmail. Just a single 
IP. I have gone through the procedures that are referenced in the return e-mails.  No response.  My next step says 
something about a $2500 fee to have it investigated.  I know several blacklists which are this way.  Luckily, many 
admins do not use such lists.
