whois/rdap of nominet refuses to disclose info about national-lottery.co.uk

camelotinteractive.com is a private registration through GoDaddy so I
had to use this nice form... no feedback so far.

Mails to the SOA email record "hostmaster at camelotinteractive.com" come
back with "unroutable email address".

whois on their IPs shows that they have a /24 and a technical contact
"Thomas Leng". Unfortunately ripe does also not simply disclose the
email address of TL3148-RIPE.

The best I could find was a marketing paper by F5 citing him how pleased
he is with his new F5 gear.
