WARNING: Whois mining operation (probably spam related).

Starting about 6am eastern time, we began getting several hundred hits per
second from
IP address to our WHOIS server.

It appears that they were running a rather well endowed dictionary against
the database.

Beware - these are spammers (I know the address very well). Check your logs
if you have
any email servers or whois databases.

This is a jerk from England who is a known fraudster.

Blueyonder / Cableinet are both owned and ran by Telewest - a cable
company, its probably a cable modem customer...

Good luck dealing with blueyonder - they won't accept complaints sent by
means other than their webform.
