Hi guys, I’m having the same problem.
I set click limit to 4, used a custom class, specified a valid URL of my site with ads, clicked “Save settings and run a check”. It all worked fine.
Then I visited my site to give it a try. I started clicking on the Adsense ads I have. Each time I clicked on an ad, I got redirected to the advertisers page in the same window/tab, so I had to use the browser’s back button to go back to my site and click on an ad again.
I did this about 6 or 7 times. I was expecting to get blocked after the fifth time but no, ads kept displaying each time I went back to my site. Clicked again two more times and ads kept showing.
Then I checked the Blocked Users list in the control panel and nothing, it was empty.
I thought it could be the minifier tool I’m using (W3 Total Caceh), so I excluded all the script files of Click-Fraud Monitoring Plugin. Tried again and nothing. I was able to click more than four times on the ads.
This is exactly how the non-minified code for the plugin looks inside the generated HTML of my site (can’t reveal my actual site’s URL here for privacy reasons):

I hope this information is somehow useful to find a solution. I really need protection against click fraud. Thanks in advance ??
