Hello!!

We are receiving a large number of spam messages in our chatbot, which we believe are generated by automatic bots. These messages include greetings and requests for sexual content. While the sexual content is relatively easy to filter out, many of the spam messages are generic and have no relation to the purpose of the chat. These generic messages are obvious bot-generated spam. We have tried to filter them out, but they still consume a significant amount of our time and tokens.

Some general info:

• Current Setup: Our chatbot is built using JavaScript and is integrated into our website.
• Impact: The spam messages are not only annoying but also consume a significant amount of our time and tokens.
• Existing Measures: We have tried basic filtering based on keywords, but it hasn't been effective in stopping all spam.
• Third-Party Services: We are open to using third-party services or libraries to achieve this, such as reCAPTCHA for CAPTCHA integration. But not sure if this is a good idea.

Has anyone else experienced similar issues with spam generated by bots? If so, what measures did you take to resolve it?

Thanks!
