Junkmail follow-up

[pseudomonas]

Junk mail has now dropped to next-to-nothing since I opted out of Royal Mail's "door-to-door" crap: http://www.stopjunkmail.org.uk/guide/door_to_door_opt_out.php - I emailed optout@royalmail.com with my name and address and asked them to send me a paper copy which I signed and posted back to their freepost address.

Has anyone tried the automated form at http://www.junkbuster.org.uk/ ?
