I have received about 20 emails from this site saying "thank you for registering for our newsletter" (which I have not!). I have tried unsubscribing, it says o.k. but the newsletters keep flying in. I have added @couponcoupon.co.uk to my blocked senders list, but the mails somehow still get through which probably means they use a fake domain. I have sent them an email to the contact address listed on their website but it got returned saying that this address does not exist. DON'T TOUCH THIS WEBSITE!
