A week or so back I requested a one off information pack via email.
I am now on their mailing list. Todays mailout had dozens of people in the To: field, their newsletter was a word attachment at 165kb (i havent opened it to see whats in it). There was no mention of unsubscribing in the email...

Thanks Pacific WiFi - you have earned my trust and respect, I really want to plonk down $2k with you now.
