there is an alert abuse link at the bottom of each post. Most alerts go to a jury of DUers to determine if the posts should be removed. If it is a complaint of an off topic post then it goes to a group of Hosts who can lock the post if it is off topic.

There is Discussion Forum Administration available at admin@democraticunderground.com or you can go to the Ask the Administrators link in the main list, immediately below the Community Link that got you here.

Edit to add link to ask the Ask the Administrators

Or do you mean those who run DU ?
