Even though I can understand your feeling about the fact that your website got cut off because of a comment, Microsoft had their right to do so. There wasn't even a disclaimer on msgstuff.com.
I recommend you get a decent disclaimer on the site, as there isn't any at the moment. Disclaimers can easily save you a lot of trouble, and a DMCA.

Of course it depends on what you write in the disclaimer.
