I really like your little Spam Catcher thing on my desktop. Catching all the IMs from people not on my buddy list is smart and a much needed product.
Unfortunately, you made it a client side tool rather than a server side tool. Therefore, it doesn't work when I forward IMs to my phone when I'm idle, because the forwarding happens before the spam catching.
Also, screenames caught in my Spam Catcher should never show up in my Recent Buddies list. I do not need to know when spammers have signed in.
