<p class="MsoNormal">I'm curious if anyone has experience deliberately buying blacklisted blocks, or blocks that otherwise have poor reputation. Is there a significant price difference? How do you seek them out? Most of the sellers I've found seem to focus
on blocks with good reputation, or on improving the reputation of a bad block. But I am interested in purchasing some IPs for internal services where reputation doesn't really matter.
