This is mIRC - so RFC 1459 has everything to do with it.
Since we aren't talking about how mIRC interfaces with the IRC server RFC 1459 has nothing to do with it.
Are are you suggesting that, because my car's manufacturer has a website that my car has to be compliant with the URL RFC :tongue: ?
If your car offers a way to recognize URLs and perform an action on them, yes.
More seriously, how many more RFCs do you expect mIRC to become compliant with, just so that some person can script some bots?
As many as are necessary for the features that mIRC offers to be fully-functional. This has more to do with a feature which mIRC offers being buggy than scripting a bot. mIRC offers a feature that makes URLs clickable so that you do not have to copy/paste them, yet it does not properly recognize URLs even though there is a concrete standard specifying how to recognize URLs.
