If you think a listing doesn't conform to ODP standards, you can click on "update URL" and explain what you think could be done.
Never mind whether it's your site or not, we won't! (That is, you can do anything for your competitor's site that you can do for your own site. The suggestions are for surfers, not webmasters, and you can make suggestions only in your capacity as surfer.)
There is no remove function. Who should we listen to for removal instructions; the webmaster, the company owner, the shareholders, a dissatisfied customer, the Pope -- what if they all disagree?
There is no removal procedure other than the site being no longer listable.
