The solution to this issue is not blist but a way to report them. Having the ease to right click, and select "Report As Spam", will go a long way to solving this issue. The report gets sent to the right hands so they can investigate. When you blist it just stays there and nobody is the wiser. The other MMO's I have played recently all have a way to report these spammers, and they hardly have a problem; this is the worst MMO I've sen in a while. You got to hit them fast, and make their pocketbooks hurt when their accounts get banned and they have to create a new one.
