I just got notified that this site has been modified to prevent cross-site scripting. Does anyone know what this means?

Cross-site scripting attacks are a leading online threat. Their aim is to exploit vulnerabilities in the websites you visit. How do they work? By compromising legitimate websites with malicious content that can capture keystrokes and record your login information and password. If your login information and password is captured, your personal data could be compromised.

Internet Explorer (IE8 and IE9) has a Cross-Site Scripting (XSS) Filter feature that can help prevent one website from adding potentially malicious script code to another website. XSS Filter analyzes how websites interact, and when it recognizes a potential attack, it will automatically block script code from running. When this happens, you will see a message in the Notification bar letting you know that the webpage was modified to help protect your privacy and security.

We should always put a link when we borrow something from elsewhere on the internet, for Adam's sake if not for our own.

I am still none the wiser.

It's simply there for the protection of yourself and other websites. I've seen people get banned from forums that continue to introduce viruses via links. A lot of times they don't even realize that they are doing it.

Then just put the name of the website at least, otherwise it looks like you are passing off someone else's words as your own (even if unintentionally) and that can take you or the site you happen to be on down the road of intellectual property law and copywrite.
