Is there a way to stop recaptcha being used on an abusive site?

Hello!I found a phishing site that uses recaptcha, though I have no idea if it's just for show or its results are actually checked. Does Google keep track on who it does not want to make use of this service?I am aware of http://bit.ly/1ft9Y0Y not of something similar for recaptcha abuse.I am looking forward to your reply! -- You received this message because you are subscribed to the Google Groups "reCAPTCHA" group.
