Re: Large number of spammer registrations
@eunos: It requires that user has to add a passcode which is pre-defined by admin and displayed in the new user registration form.
I am not sure the passcode field will help. I just enabled it and will see. Unfortunately it is easy to copy-paste the passcode and add it in the required field. But we will see.
Is there a way to add a question and answer field, like I had done in my mediawiki site? I think this is the best potential for anti-bot registration, especially (like in my case) the q + a was in my native (not english) language. No bot knows the capital of the X region of Greece or -even more- is able to write it in Greek!
