Recently active topics in Adium tagged with buddy list

I get at lot of spam messages on Adium recently. I have heard that the pc-based msn-people can choose to get messages from "only people on my list". I would like that too, because I don't really care if Becky69xyx wants to show he new fake photos to me.

In short: I would like to block spammers.

There appears to be a problem with Address book integration. Not sure if this is a new "feature" with Leopard, but it appears that you can't combine all contacts even if they are all in your Address book under the same contact name. Only two show up.
