We use mobile phone validation like a captcha, to prevent bots from signing up (since they tend not to own mobile phones.) You will be sent a validation code via text message which will be entered on the next screen. This is done just once upon signup and your personal information is not shared with anyone.
If you do not have a mobile phone or prefer not to do this, you can track down drobbins on Discord or Telegram, say hi, and have your account validated the old-fashioned way.
