Some feature questions
I have installed wpforo on my own website. but here are fake users creating by itself. how to stop it?
you need to Enable "User Registration email confirmation" option. In this case wpForo user registration function switches to WordPress Email confirmation mode. After clicking on submit button they receive Email with Password Generation link. Using this link users set a password thus confirm and finish registration process.
This option is located in Dashboard > Forums > Settings > Features admin page.
Also please read this support topic. Here you can find more information about wpForo spam control system:
