Hi Joseph,
May I know is your issue is resolved? And regarding your issue:
I have trouble locating the recaptcha setting in the back end for easy social
You need to enable recaptcha apps in EasySocial in order to use it. You can find it here: Backend > EasySocial > Applications > Recaptcha. Here is my screenshot:
