And where is usenet-news "resident"? Or "CCdeb" their payment
processor (owned by the same people): http://ccdeb.com ?
I'm sure they're kosher, but they do a bloody good job of ensuring I
wouldn't trust them with my CC details.

You're in the UK I presume, so even if there were "dodgy" transactions
appearing on your card, unless they can prove you're liable, they have
to remove them.

FWIW though, I signed up with them about 12 months ago and had no
strange activity appear on my card.
