What are you talking about? Bots to solve your captcha, they have to pay more than you pay us. What are you talking about? You have to tap at all the bots - this thing is unprofitable. And don't look at the previous owners - they said it to justify that our money was taken. You, too, will itself be justified? What are bots on your website? This is funny!
There are many people who try to cheat and can program a bot with no need of some service to solve captcha for money. For example, some days ago,
A user register on 2017-11-25, on the same day he makes 85605 satoshi and requests a withdraw. I've created a system to detect this, it is impossible to make this amount of satoshi on the same day. What did he use? a bot without a captcha service to solve it for money.
