how to block

Hi @zerocreativity !

I would be more than happy to assist you today.

The answer to your question can be found in the FAQS of the plugin itself. https://ww.wp.xz.cn/plugins/gamipress-block-users/#how%20can%20i%20block%20users%20and%20roles%3F

How can I block users and roles?
After installing GamiPress – Block Users, you will find the plugin settings on your WordPress admin area navigating to the GamiPress menu -> Settings -> Add-ons tab at box named “Block Users”.

Just choose the roles and/or users to want to prevent to getting awarded and click the “Save Settings” button.

Hope it helps!
