I've noticed that this is also happening for people who are visiting my blog, mainly because I'm using an image from IGN which I guess is labeled as a potentially dangerous site. I guess I'll remove the image and find a substitute.

However, you're not directly on the potentially dangerous website, you're only viewing an image hosted on that site. So, I guess you should have very few reasons to worry about anything.
Edit: Kk, I removed the image.

As for Desireful's site, I guess this is why it was blocked (quoted from the analytic report).

In some cases, third parties can add malicious code to legitimate sites, which would cause us to show the warning message.
