And see - you have a difficult captcha, and someone made a bot. But he made one bot and spit on your difficult captcha. Why everyone else should suffer because of this and to solve difficult captcha?
Ok, so whats the point? He spits on captcha but I have fraud system and I detect them. Again, captcha is easy, I don't set to be hard, that's not my goal.
The captcha is hard on your side because of too many solves! Try to understand this, or if you're not so techy, read more about what a captcha do.
