There is but it depends on a couple of things.
1. How do you use IGNORE. Do you just ignore by nickname or by address?
2. Consider that if the other user realises that you are ignoring them, they will find a way to evade it, such as a nickname or ISP change.
ON *:OPEN:?: {
if ($ignore($nick $+ !*@*) == $nick $+ !*@*) {
msg $nick You are being ignored.
}
}
This is just a basic script which will only work on nickname ignores. Someone else may have something more powerful. That said, I think that stealth with functions like ignore is a good practice.
