I actually got the idea from one of my favorite non-listed blogs: a combined anti-bullying and forensic psychology website with the slightly unfortunate name of Chicken Soup for the Terrorist Soul.
I like letting people post anonymously, but to prevent the paranoids ("Who is this? Is this someone I know?..."), I use Feedjit.
If you're uncomfortable being listed every time you visit, you can click on the link on the bottom "Real Time View" on the Feedjit feed and shut off my access to your IP. That's fine; all I want is a basic idea of who's visiting and whether or not it's someone who has visited before. Combined with Blogger's built-in statistics, I can use it to see if a particular blog or website is a source of people, both genuine participants and bullies.
If you're interested in Feedjit, I'd definitely recommend it. I think there's a behind-the-scenes option that you can purchase. If people have luck with that, then I'd really love to hear about it.
