Change this bit to this:
on $*:hotlink:/(@[\w-]+(\56[\w-]+)+)/:#: {
if (*Your IP Address Here* !iswm $regml(1)) {
mode $chan $iif(*!* $+ $regml(1) isban $chan,-b,+b) *!* $+ $+($gettok($regml(1),1,46),*)
}
}
Replace 'Your IP Address Here' with your real IP
You can use set it as *68.33.18* ,or shorter in one digit, for example as a wildcard. Once set, you won't be able to ban yourself. The shorter it gets, people's IP starting with 68 will not be banned.
