I just realized that, there is a method to block the Flash-based applications in Friendster profiles. This works only for users of Mozilla Firefox web browser with the Adblock Plus extension installed.

When viewing any web pages with an embedded Flash object, in this case a Friendster profile with Flash-based applications, a “Block” tab will appear either above or below the Flash object. Click on the tab and add the URL of the Flash object in the Adblock Plus block list. You may modify the URL to specify only the domain name of the URL to block all contents from the domain name. This is more effective as some of the same application is hosted over multiple subdomains.
