Are the security questions for registration necessary

[metulburr]

I made the security questions because they are the main spam prevention. The default recaptcha is wonky...sometimes shows, sometimes not...at least for me. There is a plugin for a recaptcha 3 that is bettwe, but i havent bothered since the security questions seemed to remove 100% spam. There is also no email verification. I havent set that up on the server. I havent gotten that far in my apache skills. 

The security questions i made in order to attempt that anyone can research them. And they are free to refresh for a new question there and then. And even cycle through all of them if they wish.

Of course we could use what we are doing now for spam prevention...first post moderated. Or/And we could just make them a simple math problem? 

But i definitely needed something for spam prevention with it being a ghost town...it was being bombarded by bots.
