 Jay Walsh, a spokesman for Wikipedia, flatly denied the allegations in an interview given to the "Daily Telegraph".In a story covered by "InformationWeek", Eric Goldman, assistant law professor at Santa Clara University in California argued that "eventually, marketers will build scripts to edit Wikipedia pages to insert links and conduct automated attacks on Wikipedia", thus putting the encyclopedia beyond the ability of its editors to provide countermeasures against the attackers, particularly because of a vicious circle where the strain of responding to these attacks drives core contributors away, increasing the strain on those who remain.However, Wikipedia operates to aid in the detection and removal of vandalism, and uses nofollow and a CAPTCHA to discourage and filter additions of external links.
