Hello i am running a 30 000 user forum and using Adsense since 10 years without any issue. Since mid december, my daily revenue increased by x10. I thought it was the effect of Black Friday/Cyber monday, but phenomena keeps going until the 20 of January this year. Google team suspended my acccount for illegal traffic. The 20 of February, I turned on ads display again and issue remained... I think i am victim of bot click fraud, but not able to identify them. Do you guys have an idea of to get rid of this ? Currently, i turned ads display Off and alerted Google teams about this. Thanks for reading.
You need to contact their support. I doubt anyone can help you here. Accounts do get disabled for invalid traffic: Artificial impressions and clicks that are generated through automated means such as a bot or deceptive software, are prohibited. Automated traffic can be generated by a publisher, or can be received through purchased traffic. It’s important to review traffic sources before you decide to work with a traffic source. Be aware of programs that check links within your site, YouTube channel, or app, as they may click on ad links as well. https://support.google.com/adsense/answer/2660562?hl=en
There was some WordPress plugin for blocking click fraud on ads, but I don't know what CMS you use. First talk with Adsense support, then find a solution like the one in my example to prevent future attacks.
You can alternatively use https://wordpress.org/plugins/clickguard/ to prevent the pain and frustration of losing money to click fraud. Protects Google Ads campaigns from money wasting fraudulent clicks. Hope this might help.
