I have had a moneybookers account for years, and it's on a unique email address. I've never received any spam to it, or email at all other than from moneybookers itself.
I, too, signed up for MoneyBookers with a unique email id under my dad's name. (The only place on internet I am using that combination of Name and email).And after 3 months of inactive account I was flooded with emails from random spammers. Emails sent to that unique id addressed to my dad.Don't have the emails now, but will try and look for a screenshot I saved sometime back.
