No, I do not have any other site with similar goods and what the site is offering is to some extent unique. I.e. the site is selling widgets, like other sites in this category, but the widgets are own production.
So of what you are telling me I understand that an editor could at his/her discretion drop e.g. the site of Boeing and list Airbus or list MSN and delete Google. Both examples are of companies offering the same goods and services.
Well, that may be DMOZ policy but then noone should be surprised if people start suspecting biased editing in categories with mostly commercial sites.
