I have a few sites that were penalized by Yahoo last October. It appears to be an IP block. The sites are still listed, but these same sites that used to come up in top 3 for competitive keyword terms, are now at the bottom of the stack. they are still indexed, but filtered to the bottom. Even when I search for the person's name, that we used to be number 1 for (and still are at google and Msn), our sites are filtered to the bottom.

With regards to the ip block, we are with a web host that has thousands of sites on the same ip. They are also using some type of load balancer that switches the ip's somehow.

I've read some of the info here about adding RSS feeds and blog and ping to get indexed, but what about when you are obviously penalized?

I have removed one or two sites from this ip address in the past couple weeks to see what happens, but nothing yet...

my site is www.adampascu.com, just one of the many that have been penalized at Z57 hosting
