>Forgive me for sounding naive but what did you mean by this and how did you look for it.
What was on the website wasn't under consideration at all. "Keyword stuffing" is the attempt to manipulate editors to provide poor site descriptions, in an indirect attempt to manipulate search engine results. The "usual" form includes repeated keywords, contrived use of multiple inflected forms of keywords, keyword combinations, etc.
I was assuming charitably that misspelling was just illiteracy. Now it seems we need to count it as one of the more unusual forms of keyword stuffing.
What is on your site as self-description has the single largest effect on your search engine placement. In the past, ODP descriptions have not ever been shown to affect Google placement, although many logically impaired people have been firmly and loudly convinced that they did. I still haven't seen any evidence of it, and I've looked.
There is no reason that Google shouldn't use descriptions in that way: and this summer Google is certainly using descriptions in snippet generation (which Is-Not-The-Same-Thing-At-All, note well!).
I personally suspect (from what has been said) that your SERP perp engaged in artificial link generation to attempt to promote the site; that Google (which is better than Yahoo at detecting such things) spotted it and banned the site, and that now he's using the ODP as a convenient scapegoat.
I do know how a clueful SERP perp could tell whether this was the case; I know the process by which a clueful SERP perp could repair the damage (although it might cost the illegitimately gained Yahoo position); and I can name a couple of ways that a clueful SERP per could easily work around any conceivable damage the ODP listing caused (without trying to affect the ODP or harm the ODP users in the process.)
If yours can't do this, look for a SERP perp with a clue.
