there have long been allegations that volunteer dmoz editors give favorable treatment to their own websites while concomitantly thwarting the good faith efforts of their competition. such allegations are fielded by odp's staff and meta editors, who have the authority to take disciplinary action against volunteer editors who are suspected of engaging in abusive editing practices. in 2003, dmoz introduced a new "public abuse report system" that allows members of the general public to report and track allegations of abusive editor conduct using an online form. uninhibited discussion of dmoz's purported shortcomings has become more common on mainstream webmaster discussion forums. although site policies suggest that an individual site should be submitted to only one category, as of october 2007, topix.com, a news aggregation site operated by dmoz founder rich skrenta, had more than 17,000 listings.
