Here is the facts as a I know them from running ISP mail servers as well as my own. In particular 'The Bat'.
'The Bat' is a mail header automatically raises attention since what you and I call spam, comes with it. These people don't like to be referred to as 'spammers' but email marketers for totally useless shit. There are other mass mailing
programs that do the same.
So do real girls use 'The Bat', especially if they consider themselves in the 'marketing business'. I have had perfectly legit people on our network, use email to blast others of there up and coming events. I never figured them as spammers, and they did not either, they were really semi-computer literate enough to be dangerous, but they saw nothing wrong with it. Except the one thing they overlooked, they are not the only ones who don't think there is anything wrong with it.
Marketers use the internet because it is free.... let me refer you to my blacklist page on my server...
http://www.dmsgranbury.net/dnsbl/, this is my thoughts on the matter, I doubt I will get many takers
But I do have quite a dnsbl and dsbl database, maybe I will sell subscriptions one day.
Here is a test I performed for the first time in 20 some odd years, about 1.5 weeks ago.....
You know the little flashing banners that say you won 8 godzillian dollars and a new Beemer, as well 50 of the highest end laptops? Well, I never tried one myself, until recently and always advised against clicking on them by anyone, period...
Well I used one of my spam traps, as my email address, and lo and behold, the spigot was open. My spam list has increased geometrically since. So, there are 'spammers' and 'scammers' as to which one they are sometimes, even though the 'spammer's intentions may be honest in their minds', just goes to show you, the road to hell is paved with good intentions.
These guys think they are 'marketers'. That's why I drop my po box and left no forwarding address, just notified the people that needed to know, spent more time sifting through the crap in the mail box that getting legitimate mail.
It sure is a dilemma we face. We are not in the 'Information Age' we are in the 'Age of Too Much Information'.
P.S. - I also have multiple POP accounts for my own reasons, not to spam though.
