Automated SEO Tools

I actually do not know tons about SEO automation stuff... have not really tried it. Here are some of the things I have read about

automated content generation:
ArticleBot
cloaking (such as the stuff from Fantomaster)
traffic equalizer
rss equalizer
mixes like affiliate merchant feed + rss content+ ppc backfeed

automated link generation:
guestbook bots
blog comment bots
wiki bots
distributed link networks (such as the coop ad network)
think there are lots of things you can do with rss

I am sure there will also be lots of automation talking at the ThreadWatch SEO meeting...

feel free to comment anonymously with a fake email or whatever, but what automated tools on the market do you use and find helpful?
