Fixing banned status

[learner]

I have a domain that looks like it was abused by the previous owner.

First, it looks banned by Google (not a single page in Google although it uses Google Sitemaps, etc.)
As far as Yahoo Web Search is concerned, it only has some old spam-like pages in its cache (probably old content from the previous owner):
http://search.yahoo.com/search?p=site%3Agoogle-info.com&prssweb=Search&ei=UTF-8&fr=sfp&fl=0&x=wrt

Microsoft search is the only major engine that indexes the site and rankings are quite okay considering that I don't have much content on the site.

Last week I first banned Yahoo bot in robots.txt to have Yahoo remove the old pages and after a few days I again allowed Slurp in robots.txt.
I don't know if this is enough to have the old pages removed and the site un-banned.

Is there anything else that I can do?

SE crawlers are dynamic. My personal opinion on your situation is:
-Delete all content you do not want on your new website
-Publish new content with appropriate “invitation” to the SE crawl

Remember all SE works in different ways of time, aspects, algorithms, etc.
Take a look on this good research on http://comparesearchengines.dogpile.com/OverlapAnalysis.pdf .

I think the problem is that all the cached pages do a 301 redirect.

For example:
http://www.google-info.com/Metals-3.html
returns 301.

Perhaps the correct thing is to make all these old spam URLs to return 404 to convince yahoo to forget about these bad URLs.

Thanks.

My content mgmt software can't do proper 404 and 301 so today I disallowed Slurp in robots.txt and I plan to leave it that way for 5 weeks (unless a software update solves this problem).

I have a "fake" 404 page which actually still returns a 200 response and just redirects to a 404 page. Lame, I know. I can only wait now.

It puzzles me that the Yahoo cache hadn't expired before I setup this site (although I can't find out when, how and why it was abandoned by the previous owner).
