The central policy of inviting readers to serve as authors or editors creates the potential for problems as well as their at least partial solution. Not all users are scrupulous about providing accurate information, and Wikipedia must also deal with individuals who deliberately deface particular articles, post misleading or false statements, or add obscene material. Wikipedia’s method is to rely on its users to monitor and clean up its articles. Trusted spacebar clicker contributors can also receive administrator privileges that provide access to an array of software tools to speedily fix Web graffiti and ot erious problems.
