I have several websites, but the most visited by far is IT Security News (http://www.ITSecurityNews.info). I receive a lot of spam in it which is caught by the plugin Akismet of WordPress. But, from time to time, I receive an email directed to info@ or other addresses. The latest one looks like the screenshot below and I am being offered to advertise to some newspaper for £515 pounds a month. I have no idea if this is a good offer or not, but I don’t care since I don’t make any money with this website. I couldn’t find the right business model for it so far. Still searching. So, now you see why is spam good for? It gives you an indication that your site is getting noticed. And this is very cool !
