I have a stat counter on my blog which logs the IP addresses of visitors - that way I can see where everyone's looking from. IP addresses cover a pretty large area generally, but sometimes they cover a smaller area. And even though I have all of your IP addresses, I couldn't trace you down to your exact address, unless the police were involved. And for that reason you only have to worry if you've done something wrong.
Someone has been visiting my blog, quite regularly, and each time has made a concerted effort to hide their location, via a variety of proxy sites. The fact that I know this states that your proxies aren't doing a very good job. My statistics just show the path you've taken on my blog, after your proxy address. Oh and your IP address too.
If you don't want me to see you, don't look here. It's quite simple. :)
