For maximum privacy, we encourage you to buy your ticket with bitcoin or Monero, use a pseudonym, and an email address without personally-identifying information. Also, you don’t need to enter a billing address at checkout. For the mailing address, you can make up an address, since your ticket won’t be mailed.
We will check you into the event with the email address you used to purchase the ticket(s). We will not have a list of names or pseudonyms, (and thus we will not ask for ID).
