Domain Renewal Group

[#1]

Is it possible to stop these con artists sending continuous rubbish in the post?
They are regularly trying to get me to renew my domains with them for five times what I currently pay. I have already returned their post twice and asked if they had a "do not post" list. I made it completely clear that under no circumstances will I ever transfer any domains to them so they would be best to save the paper and the postage (and the wear on my shredder). Still, they keep sending when I have a domain due for renewal in a few months.
Is this not just SPAM by post? How can this be legal in the UK?

I think you are more likely (although probably not quite so amused) to be interested in The Mailing Preference Service .
Also, threaten to report them to the BBC (specifically Anne Robinson et Watchdog)

I've heard of the swapping the contents round the reply paid envelopes, but putting in extra pennies and then demanding a refund is a nice touch!
Perhaps we could put the plastic clothes collection bags pushed through our doors by commercial firms pretending to be charities in to the envelopes!
