How to combat spam bots draining Microsoft Ads budget?

Hey everyone! So I’ve been a long time user of Microsoft ads, just recently my funds are being used up so quickly by spam bots. How do I know they are spam bots, because I have chatra which allows me to see ip, where they came from, how many visits etc. When the bot first arrives the dot is already turning Yellow, which means clicks then leaves. If I write something in the chat box the light turns green. Like it activated the bot to chat, but nothing or no one is there. I see that these bots are eating up my money now. I used to get 30k impressions per day just on Microsoft text ads, now I’m only getting $900-1000 impressions. Nothing has been changed with the ads. Like I said earlier in the post, I’ve been using Microsoft for years. Anyone else having these issues??
