Feature Request: internal captcha for unregistered user comments and registration forms
Yesterday i enabled ability to comment posts by anybody on internet (Channel Settings -> Channel role and privacy -> Custom/Expert Mode -> Channel Permission Limits- > Can comment on or like my posts -> Anybody on internet).
I think this is a very useful function that i would like to use more actively. But in a day's work (i haven't made any notifications in other networks yet, where i usually receive comments from anonymous users) - i got four comments for approval - all of them were commercial automatic spam.
I propose to consider: using a simple internal captcha to prevent this.
Also, a similar captcha in the registration form would help prevent the growth of the table
account on the hubs with registration is open.
I think that a simple graphical or arithmetic captcha will help to avoid spam registrations and spam comments of Hubzilla open forms.
