-  <small>You can ban multiple IP addresses, users, or e-mail addresses by separating entries with a single comma (User1,User2). Do not put a space after the comma. For IP addresses, you may specify ranges like 172|192.168.4-30|90-167.1-90, which will turn into 172 and 192 . 168 . 4-30 and 90-167 . 1 - 90, which matches 18,899 IP addresses. Don't specify large ranges (like the example one here) at once or you risk temporarily (~60sec) overloading the server.</small><br />
