Looks like you are trying to sign up using a disposable email address... Terrible idea! Here's why:
- Most of those services let anyone access any inbox knowing only email address. If your email address is leaked or guessed your account is compromised.
- If we get hacked or our servers/data are seized by authorities, you will never learn about it until it's too late.
- If you forget your password you'll lose your account.
We are all about anonymity, but please do it right! Use permanent anonymous email such as NotSharingMyInfo.
