I've got a few years old account with Moneybookers and didn't feel like losing it so I email them asking about their policy of bitcoin trades (for bitmarket.eu specifically). They replied:

"Please note that such transactions are restricted by Moneybookers, thus please do not attempt to make payments for them trough your profile as it could be permanently suspended"

I had heard rumors about MB accounts being closed for trading BTC, and this confirmed it for me that BTC + MB = no go zone, if you want to keep account.
