A few months ago I posted about an apparent Ban Users bug, which you confirmed and fixed. Up until today it's been working as expected with no banned user IP sniffing around. However, despite listing the complete Russian Federation IP range today I see someone within that IP range was able to access my site and peruse multiple pages. As a test to reconfirm the Banned User list was working I used Witopia to masquerade as being in Moscow and, sure enough, when I attempted to access my site it showed the expected "error" message. My question is: How could an IP from within the banned range still access multiple pages? Is this an isolated case and if so how could this be prevented in future? I can provide specific IP addresses if this would help you.
