To sign up for Deblok, join the Discord , and read the entire contents of the #what-is-this channel, then go into the #botcmds channel, then run the /signup command followed by the desired username and password (as long as it meets the requirements).
When the bot DMs you, follow and answer the CAPTCHA prompt.

You don't have to put the suffix in your Discord nickname, and do not put the Deblok suffix in the username field.
Use the Deblok suffix when signing into the Deblok servers, and NEVER put your email when logging in.
