Admiral Hosting in London

[Michael Wayne <nanog () wayne47 com>]

We were contacted by Admiral Hosting in London to rent some our
unused IP space. While they insist that they're not spammers, we can
not find out much about them.

Has anyone had any dealings with this company? Legit? Scam? We
are not interested in contributing to the Scam/Spam problem and
figured I would ask here.

As this is not, technically, NA-related, private replies are preferred.
I'll summarize to the list.
