Hi there!
My name is Kamil, I’m from the Tidio technical support, and I’ll gladly help you with your inquiry ??
I regret to inform you that creating a CAPTCHA system is not currently possible. However, you can now use the Three Dot Menu in conversations to ban users who violate your guidelines.
Alternatively, you may consider enabling a pre-chat survey feature that requires users to provide some additional information before initiating a chat. This helpful feature can assist in filtering out unwanted messages, ensuring a smoother and more productive conversation. Here’s more about it https://help.tidio.com/hc/en-us/articles/5399003714204-Start-Collecting-the-Leads#collect-data-with-prechat-survey
