I just tried to create a new account on this site Ask Ubuntu using my email and a password - and not connecting Google, Facebook etc. Filling in the display name, email and password on the https://askubuntu.com/users/signup?ssrc=head page, and pressing Sign Up would normally create an account.
But not here... Ask Ubuntu does not give any error message but nothing happens. Just like it would expect me to click some tickbox to approve my transfer of my personal data, or whatever. And yes, the password has capitals, small letters and numbers - so that's not the issue!
Finally, I had to use my G-account to sign up, which I don't like!!!
