I need an AIM, Ymess chat bot or autoresponder...

Ideally, I need a program that can automatically accept a buddy and respond based on keywords. It needs to work with Yahoo mess and AIM. It should have the ability to load hundreds of Y and AIM accounts. Please post here if you have any suggestions or PM me if you can make something like this for me...this isn't for ewhoring, btw. Harro had a "make your own bot" thread a longtime ago, but I don't think it is available here any longer.
