This is a private system where I let a few people host images for their blogs from, and a gaming clan in Runescape host their High Scores page from.
I've had the domain for almost 10 years, plan on keeping it, and don't take kindly to offers to buy it from me, increase my hit rate, or be listed in various business guides, etc...etc... It's spam. Go be "over there".
If you want a couple of useful links, here's some anti-spam files you can add to your hosts files: http://www.mvps.org/winhelp2002/hosts.txt, and http://pgl.yoyo.org/adservers/serverlist.php?showintro=0;hostformat=hosts
Read more about howto actually use those, here or here. And for God's sake people, run MalwareBytes Anti-Malware from time to time to sweep the concentrated evil out of your systems? Argentium
