Sensitive information can be sent to me by using OpenPGP encryption. Users who are not experienced with PGP can use https://keybase.io/encrypt#phantomtech to encrypt a message to me. The site will give you the encrypted version of the text, you will still have to send it using a method described here. I recommend that users who are experienced with PGP use the public key below instead of the linked site and request, though do not require, that they include a fingerprint to reply to. Once you have an encrypted message you can email it to me or send it to me on IRC where I use the cloak wikipedia/PhantomTech, do not post the message on a Wikipedia page and do not accompany it with any related unencrypted information, including in email subjects. Keep in mind that private or encrypted messages are often unnecessary, if a message has no sensitive information it should probably be posted, unencrypted, on my talk page. The few cases I can think of where a private message to me may be required or preferred are all related to ThePhantomBot and its detection algorithms.
