Hello,
A few days ago, my AdSense account was disabled because someone sends to me some fake traffic.
today I’m asking you how to block bad bots and fake traffic in WordPress, please?
Could you be more specific? what do you mean by fake traffic?
Try Wordfence. You can filter out quite good the IPs from 3rd world countries
Sure! hahahahah traffic is coming from 3rd world countries! my gosh!
Im also using wordpress but i never heard about apps blocking traffic on websites 
I mean Spam Traffic or Spam bots
someone sends it to your website to close your adsense account
They send to me 3000 visitor in 7/8/19 and my adsense account got disabled and i lost a lot of money in my account more than xxK $
