I have WP multisite and BP 2.3.2 installed. One of my sites has no BuddyPress and just a normal registration, for this one it was really easy to get what i wanted: with ""signup_extra_fields"" hook i display the captcha and with ""add_signup_meta"" hook i can validate the captcha before any data is saved to the database. But when BP is enabled on a multisite installation, there is simply no hook defined in wpmu_signup_user function found in ms-functions.php. That way it seems to be impossible to validate the the captcha with add_filter before the user is saved WP's ""signup"" table. This way one can not protect against spam registrations. Please consider adding a proper hook in WP 4.3. It is just a short line of code and can not break anything but that way the signup process would become controllable without modification of a core function." enhancement new normal Login and Registration 4.3 normal multisite
