We have implemented IntelliTXT ads. These show up as double-underlined words (versus the single underline for a regular link.) They don't do anything until you roll your mouse over them. When you do roll over them, a small window appears with an ad.

If you would like to disable these, roll over one of the links and click the "?" at the top of the popup box. This will take you to a page that explains the ads and allows you to disable them using a cookie. If you clear your cookies, the ads will reappear.
