If you spot content on this site that is genuinely illegal or actually puts someone in real danger, contact [email protected]. We have multiple agents reviewing tickets 24/7. Note that we try to maintain as much transparency as possible, both about ourselves and of the actions of Wikipedians. For example, if we removed a live link to CSAM content that was posted by a Wikipedia admin, we would replace it a placeholder like "<link to CSAM that was posted by Demiurge1000 redacted by Undersight>". Note that "I don't like it" is NOT a valid removal reason.

If instead you are a Wikipedophile trying to get all the dark secrets of Wikipedia censored, please follow this guide instead.

If you would like to contact the owner of this about something else (e.g. press inquires, feature requests, bug reports), e-mail [email protected] or [email protected].
