How do you ensure the quality of your directories?

There’s nothing that will kill the quality of one of our directories faster than having it get full of listings that link to porn, viagra, Nigerian bank account schemes, MediaMatters.org, etc. In order to filter out spam submissions to our directories, we have a set of technological barriers that filter out automated submissions, and we have a spam reporting tool that human users can take advantage of to let us know when they see something suspicious or unseemly.

Once reported, we’ll take a look at the listing and decide whether it should be deleted or if it’s legit.
