Thanks for the partial URL.

I have been having an issue with my blog being put on feeds on spam sites.
Your blog is a public blog and the contents in it are being indexed by search engines and are available to all using the internet. This is the URL for the RSS feed to your posts (entries) http://fatwaitress.wordpress.com/feed/ And this is the RSS feed to your blog comments http://fatwaitress.wordpress.com/comments/feed/
Anyone can directly subscribe to thise RSS feeds using a feedreader and you cannot prevent this when you have a public blog. In addition any wordpress.com member can click the "subscribe" button on their top gray navigation bar and subscribe to your public blog and you cannot prevent this.
If your blog content is being stolen and republished please see here for the actions you can take to have it removed. > http://en.support.wordpress.com/content-theft-what-to-do/
If that's not the case, then do be aware that anyone can link to any content you publish in a public blog in posts of their own and/or in their blogroll. The only way you can prevent other from subscribing to your feeds is to choose to make the blog "private". In that case you will not have an RSS feed and you will not be able to post social networking sharing buttons on the bottom of your posts. Please see here for Privacy Settings that control who can read your blog and take note of option #3. > http://en.support.wordpress.com/settings/privacy-settings/
Even if you do choose to have a "private" blog and choose option #2 you have no control over your official users of the blog if they choose to share the URL with others.
