How to set up automod to auto ban bots on chat?

Hi

In last few days i was struggling with bots that regurarly send similar messages with same link to the casino. I tried ban the word but message still is on the chat and i have to ban every bot by clicking on them on chat, which is annoying while playing

Is there any solution to auto ban them? For example if someone on chat mentions "X" word get time outed for X time or something?
