Hello there,
First of all, I just want to say I put 3 days in the bid but it shouldn't take that long... it's just in case of unexpected events.
Secondly, I visited your website... it seems like there's email verification and a human verification, so to fix the bot problem, I think it'd be best to improve the human verification system. In my opinion, instead of using the Captcha, we could add a random simple math equation such as "What is 2+5?" and a checkbox that ask the user "Are you a human?"... We could also keep the Inage Captcha if you'd like.
Private message me for any questions or any concerns about the price or clarifications.
