What I am saying, is that if you believe that your site really should not have been removed (or should have been added if you were submitting), then look at whether editor abuse could be the problem.
I am submitting good sites that should, and normally do, go into DMOZ without any problems. If they do not, I examine the editors involved to see if they have an ulterior motive to reject my site.
It does not take a great deal of detective work to check the editor(s) out. You will find invariably one riding shotgun on their "own" slice of the Internet.
If my memory seves me right, there have even been cases of metas (since dismissed) doing that ;)
