Wales was "...reported to be considering vetting all persons who adjudicate on factual disputes." "I don't think this incident exposes any inherent weakness in Wikipedia, but it does expose a weakness that we will be working to address," Wales added. He insisted that Wikipedia editors still would be able to remain anonymous if they wished. "We always prefer to give a positive incentive rather than absolute prohibition, so that people can contribute without a lot of hassle", Wales commented. However, he also warned that "It's always inappropriate to try to win an argument by flashing your credentials, and even more so if those credentials are inaccurate". Wales argued "contributors to the site who claim certain credentials will soon have to prove they really have them." However, Florence Devouard, chair of the Wikimedia Foundation, was not supportive of his credential suggestion, saying, "I think what matters is the quality of the content, which we can improve by enforcing policies such as 'cite your source,' not the quality of credentials showed by an editor." A formal suggestion that users saying to have qualification would have to give something to prove they really do have them, before using them was rejected by the Wikipedia community, like all previous such suggestions.
