Need recommendations for click fraud software. Dealing with one persistent person, not a bot network.
I'm hoping someone here has dealt with something similar because I'm running out of ideas.
I run Google Ads for my business and for the last few months I've been dealing with what I can only describe as targeted click fraud.
This isn't random bot traffic or competitors. I know who's doing it. It's one of my exes, and I have enough evidence outside of the click data to be confident about that. The problem isn't proving who it is, it's figuring out how to stop them from wasting my ad budget.
This person is actually pretty persistent. They'll use multiple devices, rotate IPs constantly using mobile data, and occasionally use VPNs. At one point I was able to identify one of the Android devices because it had a very distinctive browser fingerprint. Once I blocked that, the activity shifted to an iPhone. Obviously I can't just block every iPhone because that would block a huge portion of my legitimate customers too.
Over the last few weeks I've gone completely overboard trying to stop this.
I built my own visitor logger that records pretty much everything I can get from a website: IPs, user agents, timestamps, pages visited, referrers, GCLIDs, UTM parameters, and request details. I integrated FingerprintJS to identify repeat visitors when the IP changes. I set up Cloudflare WAF rules, rate limits, bot protection, and started maintaining my own blacklist of hundreds of IPs. I've tried .htaccess, Hostinger's IP blocking, WordPress security plugins—you name it.
Some of it definitely helps, but the biggest problem is that the IP address changes constantly. IP blocking alone just isn't enough when someone is determined and keeps switching networks and devices.
At this point I'm thinking the only realistic solution is dedicated click fraud software.
I'm currently looking at ClickGUARD, ClickCease, Clixtell, Lunio, ClickGuardian and TrafficGuard.
Has anyone here actually used any of these against a situation like this?
What I really care about is software that's good at recognising the same person even when they're changing IP addresses and switching between a couple of devices. I don't mind paying for it if it actually works—I just don't want to waste money on another tool that's basically just an IP blacklist with nicer reporting.
Would really appreciate any recommendations from people who've actually used these products.
