Fighting spam-bots v.2.0

Regardless of strict anti-automated-use rules implemented, some guys still attempted to use our service for their commercial (?) purposes by sending multiple automated requests and thus abusing the service.. So, we finally decided to move to "captcha" based anti-abuse protection that should cut off all those spammers completely.

Some of our users might dislike captchas, but unfortunately, the use of those is probably the only effective way to stop spam-bots. Anyway, we've done our best to develop a nice looking and easy to use and understand captcha-based interface to check page ranking instantly.

We hope you enjoy our new developments.
