getting a ton of spam user accounts

It’s been awhile and I must have messed with something somewhere…I posted about this before and the recaptcha appeared to be installed correctly before…but I have been getting a ton of spam accounts lately and I just went and checked the registration page again and I no longer see any indication of recaptcha. In the backend everything still looks set up properly. I have no idea what I may have done that may have broken it, but can someone please double check for me and tell me if I am right that it’s not actually working anymore?

It is the invisible kind, but isn’t there supposed to at least be a Google recaptcha logo?
