Let me explain better, because other people have asked.

I introduced the blacklist feature to get around broken DNS servers, that 
would drop or somehow return wrong answers for IPv6 lookups. My 
understanding is that we shouldn't talk at all to those servers and 
simply say that anything under those domains doesn't exist.

However, it was argued that some sites that are problematic are the very 
sites people want to access, such as banking sites.

Instead of adding a new blacklist, I simply moved the functionality of the 
existing one. Now it avoids sending IPv6 queries in most cases -- there 
is still one case it will send, but it's very rare and I don't think 
there's any KDE code using it. That in turn means that normal IPv4 
queries go through untouched.

The end result is that the ipv6blacklist file can no longer be used as an 
adblocker list -- a functionality it was never intended to do in the 
first place.
