Here's another data point for Moneybookers:
I also used a semi-dedicated e-mail address (minecraft@*****.com), which originally recieved e-mails from only minecraft.net. At this point, I received zero spam to this e-mail address.
I have decided to buy my friend a licence for minecraft - of which their credit card processer was Moneybookers.
I've used the above e-mail address to register for MB - this was sometime back in 2011.
After registering, I have noticed that I have been receiving casino spam e-mails to that e-mail address, containing my very unique asian first and last name.
I immediately closed my MB account, however, I still receive at least two casino spams each day, to my now dedicated MB spam e-mail address. (I have changed to minecraft e-mail address to minecraft2@*****.com
, which I receive zero spam.)
Minecraft IS a game, which may explain why I am receiving casino spam - which I think was mentioned as one of the conditions as receiving such spam.
