I have more than one gmail account; try the obvious ones based on what you know about my name and/or website. My Twitter account is kewangji. You will have to know me to send me physical letters. You may not have my phone number. My DNA will never appear in your database. Et cetera.
Writing credentials: I once made graffiti on a parkbench that was later tweeted by a relatively famous person. Then I got arrested. Don’t do drugs, kids.
