Hi I have Pie and it’s set to be activated after email confirmation and have BuddyPress as main feature. Get a new spam – user every minute. Think I need more strong reCaptcha or -I hope not – the spammer have found a loophole to pass Pie
Having Pie-Register installed doesn’t mean your User are being
registered through its system when you buddypress or any other
themes/plugins activated that provide the User registration option and
when you not let PR override default login/registration system.
For the precautionary steps, I would recommend you to turn off any other
systems’ login/registration including default/wp login/registration
pages and make them redirect over to PR login/registration pages.
