I get junk from these guys all of the time, others that have followed the 'opt-out' IMO just use it to confirm an email address for sale to others, such as themselves. Maybe I am just extra paranoid, but marketers should just stick to a web search for people that want to purchase from them.
Unsolicited email is a quagmire, email marketers do it indiscriminately. If they want to advertise on my server, ad time costs money, they can pay me for using my server for their stuff. Once it enters my ethernet port, it is mine, quite frankly, they should pay me to advertise on my servers. Their junk cost me time and maintenance, so I need to recover those costs, or blacklist them. No such thing as a 'good' spammer, JMO.
