do we contact if the category is wrong?

Some sites are being listed as swimwear/bikini, yet it is an educational site.

Im also getting some sites that arent being categorised - how do we manage these, who do we inform

Open dns has a voting system you submit a site and its added to a category

Who manages the categorys so they can be informed?

I have a workaround, the whitelist, but there are many mistakes.

You can request for recategorization from here : https://cwf.comodo.com/classify.php
