Bug reports, account deletion requests, press, moderation appeals, or a question about how something works - all of it goes to the same place.
Replies usually take a day or two. Mentioning the URL of the post or room you are writing about makes that a lot faster.
Reporting a post or an answer
Do not email us about rule-breaking content, use the Report button on the post or answer itself. It reaches the moderators with the exact item attached, so nobody has to go hunting for it, and it works whether or not you are signed in.
Account deletion
Write from the email address on the account and say what you want removed. What we store, and what happens to your posts afterwards, is described in the privacy policy.
Security
Found a vulnerability? Same address, subject line starting with SECURITY. Please give us a reasonable window to fix it before publishing, and do not access, alter or keep other people's data while testing.
