I am currently in a nightmare scenario at a new job. I just finished building their website, and it got flagged as a phishing website by Google Safebrowsing because Google seems to think that our analytics subdomain which is a self-hosted instance of Umami Analytics is a phishing attempt.
I requested a review once, they removed the flag. It came back a couple of days ago. I then had to move Umami to its own domain because I couldn't risk this ever happening again (visitors to our root domain were also getting the huge red warning, and our business was coming off as a scam).
Then they flagged the new domain as well. They've removed it again at my request, but I am just counting down the days until it happens again.
There is no way for me to get through to a human to talk about why this is happening.
They've clearly implemented prejustice, but not correctly. Find that class action lawyer and go fishing!
Have legal send Google a C&D and shoot an email to the FTC about anticompetitive behavior. That's how you get a human involved.
