List Spam Filtering

Most of the spam I've seen get through is actually obvious from the 
subject line.  I've seen more posts by people who weren't subscribed and 
asked to be cc'd than I've seen spam.  Making the list subscribers only 
would only hinder the the lucky spammers, and stop more people genuinely 
asking for help.

I have seen more spam in the past few weeks, but it's better than 
google.  For some reason, even though I don't speak anything other than 
English, email with Asian characters is not spam.
