openaccess support would be great (there should be a command like "/check 192.168.1.1" where the second part is the IP and it would list any bans applying so you could easily find stuff like "192.168.1.*"—not sure if it's a good idea to ban like this anyway, though, since that can cover a lot of people (e.g. the entire state of Iowa under my old ISP had the same two first IP parts))
Wasnt this illegal and kuji got banned for it when he made an IP banning script?
The code provided doesn't handle the IP bans; they already exist and are supported by the GServer. This is just something fancy so it's not as difficult to manage the IP bans.
