no that is nothing to do with your RSS feed. with wordpress you can set up posts to be private so that only registered members can see certain pages or posts. however, the security features of wp are not that great, and most people use membership plugins to manage these.
Rss feed is different, any one can subscribe to your Rss feed as long a s you have a button somewhere on your site for them to do it.
When people register as a member on your blog, you can choose to allow them to be a subscriber which can read private posts that are not available to the general public, a contributor, where they submit content and you can aprove it to be posted, (great for if you are having guest posters on your blog), you can make them an author which allows them to make posts, you can set them up as an editor which allows them to post or edit any post within the blog, or they can be an admin which can do anything that you can do.
most of the spam people who join blogs randomly do so to access private pages, or they are hackers. I f a hacker breaks into your blog, they can get into your hosting server, and ruin everything.
Now, some people make a huge deal out of it because wp is easy to hack (any open source software will be) but the fact is the % of people that it actually ever happens to is very low.
