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].

However, personal experience differs between individuals. In other words, we don't know for sure if we '''know''' something or if it just result of our personal experiences. The scientific method is a strategy that helps us know that we know something, and sometimes, to know that we were actually thinking wrongly the whole time. I don't want to simply "know something" -- I want to '''know''' that I know something. So, I've chosen to dedicate my work to doing science and talking about it.'' | about me = Hi.
