Fediseer

There are 4 interesting attributes (which makes Fediseer quite useful because no other dataset captures this level of detail):

• open_registrations
• approval_required
• email_verify
• has_captcha

When running select open_registrations,approval_required,email_verify,has_captcha from FSnodeTbl where open_registrations = 0 | sort -u`, we get all varieties of combinations:

AFAICT, the value of open_registrations is not implied by the other variables. It seems to be an independent variable that should mean just what it describes on the face of it.

And if we consider just cases where open_registrations is true, there are fewer combinations, strangely, but still it’s independent of approval_required (2nd column):
