Please start sending us URLs!
IMPORTANT! You aren't sending us URLs of the site where captcha is solved.
Now, when we receive the URL form our client, we send our worker to that site, where he gets the captcha, solves it and returns the token back to us. When we don't have your URL we can use a certain security flaw and still get the token. All was good, but our google insider tipped us off that in the nearest future this flaw will be fixed and recaptcha will become solvable only on the site where it is supposed to be.
Please consider this information and change your uploading algorithm to include sending us your URLs.
P.S. And if you don't want to receive any more news from us you can always unsubscribe :(.
