Opting out of "To the Occupier" junk mail from Virgin

If you get "To the Occupier" junk mail from Virgin Media in the UK, you can opt out by emailing them on twitter@virginmedia.co.uk ^* . I did this and the torrent of junk mail seems to have abated.

Dear Virgin Media,

I would like you to stop sending "To the Occupier" junk mail to my address:

[address here]

Yours faithfully,

If you're getting junk mail addressed to you by name (from Virgin or any other company), you should instead register with the Mail Preference Service. If you want to opt out of unaddressed junk mail, see the Royal Junk Mail site for details.

^*They provided the email address via twitter. A reply to the email came from EComplaints@virginmedia.co.uk.
^**Some browsers seem to have a bug whereby they convert the email body to all lower-case. Apologies if this is the case for you.
