Huh?  Maybe things are different where you live, but in this part of
the world, registrars like Godaddy have millions of customers and know
nothing more about them than that their credit card charge for $8 was
approved.  It's hard to imagine how anyone could think that a
registrar would know anything at all about its customers mailing
practices.

To put it concretely, your registrar is JANET, which is a fairly
reputable organization.  Are you claiming that means that ADSP
published by random ac.uk subdomains are all going to be accurate and
useful?
