Wikipedia co-founder Larry Sanger has been barred from editing the site indefinitely. Reporting on the decision says the ban was imposed after volunteer editors accused Sanger of violating Wikipedia rules by attempting to influence an internal discussion using followers outside the encyclopedia (often described as “off-wiki canvassing”).

Sanger’s supporters and opponents have framed the dispute around his efforts to push for recognition of “WikiProject Intellectual Diversity,” a group he promoted as a way to reinforce neutrality and broaden participation. A Wikipedia page documenting his status reportedly indicates the block is set to remain indefinite and links to a discussion about whether his actions crossed the line.

In accounts of the ban, Sanger pointed to procedural fairness concerns, while other editors argued there was consensus that his conduct wasn’t constructive or in line with Wikipedia’s policies. The coverage also notes that Sanger had publicly described the situation as lacking due process, and he criticized the decision-making process.
