I've been asked to be clear about my understanding of Google Answers.
I understand that researchers are not employees of Google. However I
would still like Google researchers to provide me an answer. My
question was 378222.

Here is it again, stated a bit differently.

A few domains with which I am now associated were part of a link farm.
The owners of this domain did not know what was going on. Their host
suggested they go with a different company once he discovered (we
think) that he was banned by Google.

Can these ladies keep their same domains and as long as they are on
different ip addresses will Google reinstate their domains? If so what
type of time frame can be expected? Or should they just cut their
losses and create new domains for which to sell their items.

Domains affected are:
