Your website is infected with mal-ware
About 1/3 of the time I load a page, my browser (chrome) stops loading it and gives me a warning.
"Content from ads.zitaholdings.com, a known malware distributor, has been inserted into this web page. Visiting this page now is very likely to infect your computer with malware."
Needless to say, this isn't what I expect of a site as old and respected as yours.
Discretion is the greater part of Ninja.
