utorrent - something seems odd

Good afternoon geeks, I'm running XP Home SP3
I noticed something in utorrent today that seems odd...
On the bottom part of the window there are a series of tabs, I was watching the speed tab with upload and download selected and noted the upload at a higher rate, which is OK because I'm sharing. So I go to the peers tab and note the following:
1) there are four peers with IP addresses only 1 number apart, the last number
2) in the client column for those peers it reads [FAKE] utorrent
3) in the amount uploaded column, it appears that 85% of all uploaded MB's has gone to these 4 peers
4) these peers are only uploading, they are not downloading anything, speed is 0

So do I have some bad guys, or a big leecher? It doesn't appear that I can do anything about it, I find no command to block or delete this guy.

Your thoughts?
