I'm just wondering if anyone ever wrote a tool to optimize the various huge lists provided by different people or even self built lists... What do I mean by optimize? When the list is of type dstdomain and contains entries: www.domain.ex www2.domain.ex www-dumb.domain.ex x.www.domain.ex www3.domain.ex If you know that domain.ex is actually a domain of whatever the list type is you can just change all those entries into one .domain.ex entry...
