Disable history tracking of blocked screen names

[RotJ]

I 've noticed that some people have been complaining about the spam IMs they've been getting. Generally, I get a single spam each time I log on. I just hit block and that takes care of it until the next time I get on AIM (which is much better than getting a spam every 30 minutes back when I had free AOL). Each one of these spammers get listed in my history and I have to ferret them out and delete them to keep my history menu from being filled by spammer names. It would be nice to be able to have blocked screen names deleted from the AIM+ history list or kept in a separate blocked menu item to keep them grouped together.
