I've got a hotmail account and until recently I've not received any spam. But now I'm getting a series of message, always in the same style but from different addresses, offering Morrison vouchers, ASOS vouchers, credit cards etc etc. I'm moving them to Junk in the hotmail desktop and in Outlook I'm marking as Junk and 'Blocking sender' to no avail. There is an unsubscribe link at the bottom of each email but I'm concerned that if I click that it will just confirm that mine is an active email address.
Any advice on what else I can do please?
