There are no official stats, thus we can't delete you from any; stats are entirely something the server admin does. I removed you from the RBI server stats as good as possible, though. In the future, your nickname will get replaced by "anonymous" and anonymous players don't enter the top/bottom records category at the bottom of the stats page.
According to Google, you are on DCC's stats too - to get removed, it would be best to send DCC an email to do so. The mail address is on the bottom of DCC's websites.
If the stats tracking of the RBI server is generally unwanted, I'll tone it down to just report weapon stats, which is the main reason why it is running. As for where the RBI stats are,

1. Open Notepad
2. Paste: ÿþMSMSMS
3. Save
4. Open the file in Notepad again
You can vary the number of "MS", so you can clearly see it's MS which is causing it.
