Everything here reaches a person. There is no ticketing system and no autoresponder, so give it a day or two.
Asking for your data, or for your account to be deleted? Pick that option below. Deletion removes your account, your comments and your votes, and is handled within thirty days. Tell us which account you used to sign in — the name you comment under is usually enough to find it.
Comment removed and you think it should not have been? Say which post it was on and roughly what you wrote. Moderation is automated and does get things wrong.
